I am not the one putting limits on what Christ can do, you are. And why would what I say give you concern? It is without a doubt possible for Christ do exactly what I said. The only wooden thing is when men think that every single doctrine which comes out of the RCC is infallible.
What is wooden is this chronic redefinition of terms like "doctrine" and "infallible". Using the same terms with entirely different meanings is what makes discussions like these so frustrating. In order for anything to be a doctrine, it must flow from what has been divinely revealed from Jesus and the Apostles, by word or letter. Infallibility is a gift from God that prevents teaching on faith and morals from falling into error.
Matt. 10:20; Luke 12:12 – Jesus tells His apostles it is not they who speak, but the Spirit of their Father speaking through them. If the Spirit is the one speaking and leading the Church, the Church cannot err on matters of faith and morals.
Matt. 16:18 – Jesus promises the gates of Hades would never prevail against the Church. This requires that the Church teach infallibly. If the Church did not have the gift of infallibility, the gates of Hades and error would prevail.
Matt. 16:19 – for Jesus to give Peter and the apostles, mere human beings, the authority to bind in heaven what they bound on earth requires infallibility. This is a gift of the Holy Spirit and has nothing to do with the holiness of the person receiving the gift.
Matt. 18:17-18 – the Church (not Scripture) is the final authority on questions of the faith. This demands infallibility when teaching the faith. She must be prevented from teaching error in order to lead her members to the fullness of salvation.
Matt. 28:20 – Jesus promises that He will be with the Church always. Jesus’ presence in the Church assures infallible teaching on faith and morals. With Jesus present, we can never be deceived.
Luke 22:32 – Jesus prays for Peter, that his faith may not fail. Jesus’ prayer for Peter’s faith is perfectly efficacious, and this allows Peter to teach the faith without error (which means infallibly).
1 & 2 Peter Peter denied Christ, he was rebuked by his greatest bishop (Paul), and yet he wrote two infallible encyclicals. Further, if Peter could teach infallibly by writing, why could he not also teach infallibly by preaching? And why couldn’t his successors so teach as well?
Gen. to Deut.; Psalms; Paul – Moses and maybe Paul were murderers and David was an adulterer and murderer, but they also wrote infallibly. God uses us sinful human beings because when they respond to His grace and change their lives, we give God greater glory and His presence is made more manifest in our sinful world.
John 14:16 – Jesus promises that the Holy Spirit would be with the Church forever. The Spirit prevents the teaching of error on faith and morals. It is guaranteed because the guarantee comes from God Himself who cannot lie.
John 14:26 – Jesus promises that the Holy Spirit would teach the Church (the apostles and successors) all things regarding the faith. This means that the Church can teach us the right moral positions on such things as in vitro fertilization, cloning and other issues that are not addressed in the Bible. After all, these issues of morality are necessary for our salvation, and God would not leave such important issues to be decided by us sinners without His divine assistance.
John 16:12 – Jesus had many things to say but the apostles couldn’t bear them at that point. This demonstrates that the Church’s infallible doctrine develops over time. All public Revelation was completed with the death of the last apostle, but the doctrine of God’s Revelation develops as our minds and hearts are able to welcome and understand it. God teaches His children only as much as they can bear, for their own good.
John 16:13 – Jesus promises that the Spirit will “guide” the Church into all truth. Our knowledge of the truth develops as the Spirit guides the Church, and this happens over time.
1 Cor. 2:13 – Paul explains that what the ministers teach is taught, not by human wisdom, but by the Spirit. The ministers are led to interpret and understand the spiritual truths God gives them over time.
Eph. 4:13,15 – Paul indicates that attaining to the unity of the faith and the knowledge of the Son of God to mature manhood is a process. We are to grow up in every way into Christ. Doctrine (which means “teaching”) develops as we understand God’s Revelation.
Acts 15:27-28 – the apostles know that their teaching is being guided by the Holy Spirit. He protects the Church from deception.
Certain ecumenical councils, or parts thereof, are infallible. They are modeled after the infallible Council of Jerusalem (Acts 15). Cherry picking from the infallible Council of Nicae, 325, are errors of omission.
