ok, this is completely getting of the topic of the thread. Maybe you should start your own on the infallibility of the Church on matters of faith and morals.
“In order to preserve the Church in the purity of the faith handed on by the apostles, Christ who is the Truth willed to confer on her a share in his own infallibility”(CCC 889). “Go and make disciples of all nations…teaching them to observe all that I have commanded you; and lo, I am with you always”(Mt 28:18-20); “Whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven”(Mt 18:18); “He who hears you hears me, and he who rejects you rejects me”(Lk 10:16); “When the Spirit of Truth comes, he will guide you into all the Truth” (Jn 16:13).“hold fast what you have, until I come”(Rv 2:25), “guard what has been entrusted to you” (Tm 6:20)
“The infallibility which the divine redeemer wished to endow His Church in defining doctrine pertaining to faith and morals, is co-extensive with the deposit of revelation”(Vatican Council II, Dogmatic Constitution on the CHurch, Lumen Gentium, 25;cf. CCC 2035).
“It is this Magisterium’s task to preserve God’s people from the objective possibility of professing the true faith without error…To fulfill this service, Christ endowed the Church’s shepherds with the charism of infallibility in matters of faith and morals” (CCC 890).
