He who believes and is baptized will be saved. (Mk 16:16)
[U]nless you repent you will all likewise perish. (Lk 13:3
[H]e who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. (Jn 6:54)
So, do listen to the words of Jesus who said it is faith+ repentance+baptism+the Eucharist+endurance, not any of these in isolation. Of course, these don't "save us" per se, since it is Christ's sacrifice on the Cross that grants us our salvation that we can accept or reject.
Is there such a thing as a ‘deathbed confession of faith’ and, if so, is that enough to ‘save’ and/or ‘justify’ us?
