You convieniently left of the rest of post. I clarified that truths must be taught.
The crux of the matter is WHAT is taught as “truths” – as the Sacred Scriptures teach:
The Church is “the pillar and bulwark of the truth (1 Tim 3:16).” St. Paul says also, “through the Church the manifold wisdom of God might now be made known to the principalities and powers in the heavenly places (Eph 3:10).” The Church teaches even the angels! This is with the authority of Christ! We are redeemed by Christ’s Passion and Death (heaven was opened); we are not saved until we co-operate with Him.
The reality here is concerning the truths of the Catholic Church which Christ established on St Peter as His Supreme Vicar and His Apostles, sending the Holy Spirit as He promised: “I will not leave you orphans; I will come to you." (John 14:15-18) “The Advocate, the Holy Spirit that the Father will send in My name, He will teach you everything and remind you of all that I told you.” (John 14:26) “But when He comes, the Spirit of truth, He will guide you to all truth. He will not speak on His own, but He will speak what He hears, and will declare to you the things that are coming. He will glorify Me, because He will take from what is mine and declare it to you. Everything that the Father has is mine; for this reason I told you that He will take from what is mine and declare it to you.” (John 16:13-15)
Thus, from the first, the faithful “remained faithful to the teaching of the Apostles, to the brotherhood, to the breaking of bread, and to the prayers.” (Acts 2:42).
Therefore, brothers, stand firm and hold fast to the traditions that you were taught, either by an oral statement or by a letter of ours." (2 Thess 2:15).
“Take as your norm the sound words that you heard from me, with faith and love that are in Christ Jesus. Guard this rich trust with the help of the Holy Spirit that dwells within us.” (2 Tim 1:13-14). Again St Paul writes: “And what you heard from me through many witnesses entrust to faithful people who will have the ability to teach others as well.” (2 Tim 2:2).
In Colossians 2: 4-23, St Paul calls on his flock to follow Christ “as you were taught” and warns against merely “human precepts and teachings.”
1 Cor 1:10: I urge you brothers, in the name of Our Lord Jesus Christ, that all of you agree in what you say, and that there be no divisions among you, but that you be united in the same mind and in the same purpose.
We are of God. He who knows God hears us; he who is not of God does not hear us. By this we know the spirit of truth and the spirit of error. (1Jn 4:6).
Secondly, are you telling me Protestants can’t or aren’t “saved” from eternal damnation because they don’t participate in the sacraments?
She is the only means of salvation provided by Christ and those who come to see this will ensure their assent to Her teaching and join in Her sacrificial worship and Her sacraments for their salvation. Those who don’t yet see this MAY be saved by following their conscience in endeavoring to know and follow the will of God; some will come home, or return, to Christ’s Church – which means that culpable ignorance or rejection do not suffice. Once anyone knows what Christ wants through His Church they have the free choice to follow Him, or to reject Him with the inevitable consequences.
Why should anyone willfully want to deny Christ’s teaching for their salvation?
