One of the things which was brought up by one of the Protestants in that thread is this idea that St. Constantine started the Catholic Church. But, is that true? Why do Protestants make this claim?
The short answer, “I don’t know.” The claim is patently false and can be proven directly from the New Testament. And, although the Bible was not put together until after St. Constantine’s death, yet the New Testament was already written although not compiled.
And while the name, “Catholic Church” is not written in those pages, yet, the Catholic Church is therein described. And if the Catholic Church is described in the New Testament, then it must be the Church established by Jesus Christ. AND, lest we forget, what we don’t find is any of the Protestant denominations there mentioned. Nor any of their doctrines. Without further ado, let's see what Scripture says.
First, Jesus Christ appointed a Pastor as head of the entire Church: John 21:17 He saith unto him the third time, Simon, son of John, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.
I see only a few Churches with such a Pastor. Further, Jesus Christ said that the Pastor over His Church would be infallible:
Matthew 16:17And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.18And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. 19And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
The list of Churches accept this teaching gets smaller. Certainly, all Protestant denominations can now be eliminated.
Jesus Christ not only said that the Pastor was infallible but Scripture describes the Church as infallible: Ephesians 3:10 To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,
The list remains the same, but now I can certainly eliminate all Protestant denominations.
Back to Matt 16:18, Scripture says that Jesus Christ established one Church. History shows that all the Churches sprang from the Church which is frequently described as the Mother Church. The Catholic Church.
So, even using just a few verses we can eliminate the Protestants. None of their denominations even come close to being in Scripture. But we can continue to find Catholic indicators throughout the Bible:
The Church which is infallible (1 Tim 3:15; Eph 3:10). The Church which is united (Eph 4:5). The doctrines of the Catholic Church which are distinctive from other churches: Purgatory (1 Cor 3:15). Eucharist (1 Cor 11:23-27). Communion of Saints (Rom 12:12-20). The Mass and the necessity to attend (Heb 10:25-31). The Sacrament of Confession (Heb 13:17). The Sacrament of Holy Orders (1 Tim 4:14). The Sacrament of Baptism (Titus 3:5). Justification and salvation by faith and works (Rom 2:1-13).
And we find that the Protestant doctrinal pillars all contradict Scripture. For instance:
Sola Scriptura contradicts 2 Thess 2:152 Thessalonians 2:15 King James Version (KJV) 15 Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
Sola Fide contradicts James 2:24 James 2:24 King James Version (KJV) 24 Ye see then how that by works a man is justified, and not by faith only.
OSAS contradicts Heb 6:4-6 Hebrews 6:4-6 King James Version (KJV) 4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,5 And have tasted the good word of God, and the powers of the world to come,6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
Salvation by grace alone contradicts: Philippians 2:12 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
Romans 6:16 Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
Every Protestant doctrine which contradicts the Catholic Church also contradicts the Word of God in the Bible.
So, the fact that Jesus Christ established the Catholic Church is recorded in the New Testament. And Protestants nor their doctrines are anywhere to be found in those venerable pages.
