“That is the Catholic way of salvation..”
And the Orthodox and in part the Anglican and Lutheran, in fact almost all of Christianity for almost all of history has believed what you dismiss so glibly.
Good luck with that.
Jesus said to them again, Peace be with you. As the Father has sent me, even so I send you. And when he had said this, he breathed on them, and said to them, Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.
Well, I am truly sorry you will not listen.
God wants none to perish but you simply will not be budged.
Remember me on the last day and remember that I did speak truth.
Acts 15:8 And God, who knows the heart, bore witness by granting them the holy Spirit just as he did us. 9 He made no distinction between us and them, for by faith he purified their hearts.
