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.
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.
