In a world characterised by numerous branches of the Christian faith, it is easy to assume that all individuals share identical beliefs regarding the Bible, albeit with varying approaches to their faith. The two predominant denominations within Christianity are generally recognised as Protestantism and Roman Catholicism. Nonetheless, there exist a vast array of sects within both Protestantism and Catholicism. There is a movement called ecumenism, which seek to unity all Christians around the world regardless of what they believe.
This idea that Christians from different denominations should work together to promote unity and closer relationships between their churches is not based on the teachings of the Scriptures. In Scripture, there are no denominations. It is my belief that Christians ought not to recognise “denominations” and simply just call themselves “Christians” rather than, “Presbyterian”, “Baptist”, “Methodist”, and so on. Denominations are man-made and our faith and fellowship ought to be based on our common faith rather than a denominational title or club.
Those who embrace the message of ecumenism seek to acknowledge Roman Catholics as Christians. Today, we will examine the official teachings of the Roman Catholic Church as derived from their own authoritative sources and ascertain whether Roman Catholicism qualifies as a genuine Christian religion.
The Gospel According to the Roman Catholic Church
The Bible says in Romans 3:23 “For all have sinned, and come short of the glory of God.” To be reconciled to God, sinners must come to God by faith and embrace the free gift of salvation. Romans 5:8 says, “But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.” Romans 10:13 says, “For whosoever shall call upon the name of the Lord shall be saved.” The Bible is clear that no person receives forgiveness of sin through works. Ephesians 2:8–9 says, “For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.” Salvation is a gift from God, so no one can boast.
According to the official doctrine of the Roman Catholic Church, the process of salvation is quite demanding. Roman Catholicism outlines various steps toward salvation, including actual grace, faith, good works, baptism, engagement in the sacraments, penance, indulgences, and adherence to the commandments. In summary, this indicates that the Roman Catholic Church believes salvation is contingent upon one’s actions and individual efforts to attain justification before God.
The Teaching of Faith
Faith is central to the Gospel, but according to Roman Catholic teachings, it’s merely one aspect of salvation. The Roman Catholic Catechism affirms, “Faith is necessary for salvation. the Lord himself affirms: “He who believes and is baptised will be saved; but he who does not believe will be condemned” (Mk 16:16)” (CCC 183).
This is correct and proper; faith is undeniably essential for salvation. Nevertheless, Catholicism does not rest its beliefs solely on faith. It incorporates works alongside faith, treating faith as a point of initiation rather than the cornerstone of salvation. Additionally, Catholic doctrine includes the traditions of “the Church.” As stated in the Catholic Catechism, “outside the Church there is no salvation.” Consequently, the Roman Catholic Church asserts that other churches lack legitimacy and claim to be the one true Church on earth, often designating itself as “the Mother Church.”
The Roman Catholic Catechism states in CCC 846. “How are we to understand this affirmation, often repeated by the Church Fathers? Re-formulated positively, it means that all salvation comes from Christ the Head through the Church which is his Body: Basing itself on Scripture and Tradition, the Council teaches that the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is the mediator and the way of salvation; he is present to us in his body which is the Church. He himself explicitly asserted the necessity of faith and Baptism, and thereby affirmed at the same time the necessity of the Church which men enter through Baptism as through a door. Hence they could not be saved who, knowing that the Catholic Church was founded as necessary by God through Christ, would refuse either to enter it or to remain in it.”
The Doctrine of Baptism
Scripture informs us that all born-again believers in the Lord Jesus Christ should partake in believers’ baptism as an act of obedience and a way to associate themselves with the Lord and His Church. It is important to note that baptism should not be viewed as a means of achieving salvation or as a method for earning it. Baptism does not provide justification for a sinner in the eyes of God. Only faith in the sacrificial blood of Christ on the cross can grant a sinner’s salvation. The Roman Catholic Church, however, connects baptism to the process of justification.
“Justification has been merited for us by the Passion of Christ. It is granted to us through Baptism. It conforms us to the righteousness of God, who justifies us. It has for its goal the glory of God and of Christ, and the gift of eternal life. It is the most excellent work of God’s mercy.” (CCC 2020)
“The Lord himself affirms that Baptism is necessary for salvation. He also commands his disciples to proclaim the Gospel to all nations and to baptise them. Baptism is necessary for salvation for those to whom the Gospel has been proclaimed and who have had the possibility of asking for this sacrament. The Church does not know of any means other than Baptism that assures entry into eternal beatitude; this is why she takes care not to neglect the mission she has received from the Lord to see that all who can be baptised are “reborn of water and the Spirit.” God has bound salvation to the sacrament of Baptism, but he himself is not bound by his sacraments. (CCC 1257)
As evidenced by the excerpts from the Roman Catholic Catechism, it is indicated that baptism is a prerequisite for salvation and constitutes a vital sacrament through which salvation is bestowed.
During the 16th Century, the Reformers severed ties with the Roman Catholic Church, denouncing its erroneous gospel. The Protestants opposed the practice of selling indulgences—which can be understood as the commercialisation of salvation—and the unbiblical customs associated with Roman Catholicism. In response, the Roman Catholic Church countered the Reformers’ movement with a formal declaration issued by the Council of Trent (1545 – 1563), which included condemnatory language directed at the Protestants. It is important to recognise that the term “anathema” was deliberately used to signal that individuals who accept Protestant beliefs are regarded as condemned to eternal damnation by the Roman Catholic Church.
Here are some key statements that were officially published by the Roman Catholic Church at the Council of Trent.
On Justification: The Council of Trent denounced the idea of justification by faith alone, emphasising the necessity of works: “If anyone says that the justice received is not preserved and also not increased before God through good works, but that those works are merely the fruits and signs of justification obtained, but not the cause of its increase, let him be anathema” (Session 6, Canon 24).
On Sacraments: In regard to the sacraments, the Council reaffirmed the efficacy of the sacraments for salvation and anathematised those who denied their importance: “If anyone says that these sacraments of the New Law do not differ from the sacraments of the Old Law, except that the ceremonies are different and the external rites are different, let him be anathema” (Session 7, Canon 1).
On Transubstantiation: The Council affirmed the doctrine of transubstantiation and anathematised those who rejected it: “If anyone denies that in the sacrament of the most Holy Eucharist are contained truly, really and substantially the body and blood together with the soul and divinity of our Lord Jesus Christ, and therefore the whole Christ, let him be anathema” (Session 13, Canon 1).
On Good Works and the Human Will: “If any one saith, that by faith alone the impious is justified; in such wise as to mean, that nothing else is required to co-operate in order to the obtaining the grace of Justification, and that it is not in any way necessary, that he be prepared and disposed by the movement of his own will; let him be anathema” (Council of Trent, Canons on Justification, Canon 9).
Observe how “faith alone” is distinctly targeted in their doctrine. They strongly contest the Scriptural teachings that state salvation is attained solely through faith in Jesus Christ. Additionally, they assert that human will plays a role in preparing and collaborating with God to achieve justification, which contradicts Scriptural teachings. To this day, the Roman Catholic Church does not recognise Protestant Christians as fellow brothers and sisters in Christ. Thus, what rationale do we have for considering Roman Catholics as Christians?
Sola Scriptura and the Roman Catholic Church
At the time of the Reformation, the Reformers issued a set of five fundamental statements, which served as markers to clarify their positions on essential doctrines of the faith. These statements are collectively referred to as the “five solas” of the Reformation.
- Sola Scriptura (Scripture Alone)
- Sola Gratia (Grace Alone)
- Sola Fide” (Faith Alone)
- Solus Christus (Christ Alone)
- Soli Deo Gloria (To God Alone Be Glory)
The Bible is entirely adequate to furnish us with all that is essential for genuine faith and adherence to God. The principle of Sola Scriptura is deliberately prioritised, as any compromise in one’s understanding of Scripture can lead to subsequent distortions in other essential doctrines, including those of salvation and the church. Undoubtedly, the Roman Catholic Church’s rejection of Sola Scriptura results in significant errors in worship, particularly evident in their practices of praying to saints and their elevation of Mary to a role as co-Redemptrix. At the Council of Trent, the Roman Catholic Church explicitly targeted this fundamental doctrine of Sola Scriptura in an official capacity.
On Tradition and Scripture: The Council defended the authority of both Sacred Tradition and Scripture and anathematised those who rejected this dual authority: “If anyone does not accept the entire books with all their parts … as they have been accustomed to be read in the Catholic Church … let him be anathema” (Session 4, Canon 8).
The Church of Jesus Christ has historically upheld the principles of the inerrancy, infallibility, authority, and total sufficiency of Scripture. Conversely, the Roman Catholic Church makes the significant error of incorporating its own traditions alongside Holy Scripture. Indeed, it elevates these traditions to a status equivalent to divine authority. Consequently, when the Roman Catholic Church formally acknowledges a teaching as true—regardless of the biblical perspective—it is regarded as sacred, holy, divine, and authoritative.
Throughout the course of church history, the Roman Catholic Church has endeavoured to maintain dominion over the Bible. They harboured animosity towards figures such as John Wycliffe and ultimately executed William Tyndale due to their contributions in translating the Scriptures into vernacular languages. The liberation of the Bible in the language of the common people, initiated by Martin Luther in German and subsequently by William Tyndale in English, diminished the Roman Catholic Church’s authority. This marked the inception of the Reformation. Consequently, the populace was able to comprehend the Scriptures as they were read and preached. The Roman Catholic Church continues to strive for control by ensnaring individuals with their traditions, elevating them to a status equivalent to divine Scripture.
Paragraph 80 of the Roman Catholic Catechism states, “Sacred Tradition and Sacred Scripture, then, are bound closely together, and communicate one with the other. For both of them, flowing out from the same divine well-spring, come together in some fashion to form one thing, and move towards the same goal.” Each of them makes present and fruitful in the Church the mystery of Christ, who promised to remain with his own “always, to the close of the age”.
Paragraph 82 states, “As a result the Church, to whom the transmission and interpretation of Revelation is entrusted, “does not derive her certainty about all revealed truths from the holy Scriptures alone. Both Scripture and Tradition must be accepted and honoured with equal sentiments of devotion and reverence.”
Worship of Mary
I would like to briefly discuss the role of the Mother of Jesus within the Roman Catholic faith. The Catechism of the Catholic Church emphasizes in paragraph 972, “After addressing the Church’s origin, mission, and ultimate purpose, we find no more fitting conclusion than to turn our attention to Mary. In her, we reflect on the Church’s current mystery during her own ‘pilgrimage of faith’ and its future state in the heavenly homeland. There, ‘in the glory of the Most Holy and Undivided Trinity,’ ‘in the communion of all the saints,’ the Church is awaited by the one whom she honours as the Mother of her Lord and her own mother.” In Roman Catholicism, Mary is regarded as a central figure of devotion and reverence, often referred to as “the Queen of Heaven.”
The Doctrine of Transubstantiation
The final point I would like to make is the Roman Catholic doctrine regarding the Lord’s Supper.
“The mode of Christ’s presence under the Eucharistic species is unique. It raises the Eucharist above all the sacraments as “the perfection of the spiritual life and the end to which all the sacraments tend.” In the most blessed sacrament of the Eucharist “the body and blood, together with the soul and divinity, of our Lord Jesus Christ and, therefore, the whole Christ is truly, really, and substantially contained.” “This presence is called ‘real’ – by which is not intended to exclude the other types of presence as if they could not be ‘real’ too, but because it is presence in the fullest sense: that is to say, it is a substantial presence by which Christ, God and man, makes himself wholly and entirely present.” The official teaching of the Roman Catholic Church is that Christ is actually and really present in the elements of the bread and wine. The Catholic Church teaches that Christ is offered as a sacrifice for sin in the elements of the Lord’s Supper. This teaching is contrary to Scripture. Hebrews 9:28 states that Jesus Christ was offered once to take away the sins of many.
Closing Statement
We have explored only a limited number of doctrines within the Roman Catholic faith. This analysis constitutes merely a small fraction of a much more extensive issue. There exists significantly more that could be written regarding the various inaccuracies pertaining to Roman Catholicism. However, my purpose is not to inundate you with an overwhelming amount of information on this topic. Instead, I intend to furnish you, the reader, with adequate information to illustrate that Roman Catholicism is not in agreement with biblical Christianity on fundamental doctrines such as faith and salvation.
I would also like to clarify that I do not consider myself a “Protestant.” The Protestants were individuals who, while being Roman Catholics, protested against the official doctrines of the Roman Catholic Church. As I have never been a member of the Roman Catholic Church, I have not opposed its official teachings from within that religious framework.
Prior to my conversion to faith in Christ, I held Roman Catholic beliefs and doctrines in high esteem. During my adolescence, I contemplated the possibility of becoming a Roman Catholic. I identified as an Anglo-Catholic before I was saved by God’s grace. Anglo-Catholicism is a movement within the Anglican Communion that stresses the Catholic heritage of the Church of England.
It is essential for all born-again believers in the Lord Jesus Christ to identify solely as Christians. Our authority in all matters of faith and practice derives exclusively from the Word of God, rather than from human teachings and traditions.
