All of them living, breathing fellow Christians.
The dead do not hear your prayers.
You are wrong because you know neither the scriptures or the power of God. Have you not read what was said to you by God “I am the God of Abraham, and the God of Isaac, and the God of Jacob?” He is not God of the dead but of the living.
The point seemingly being that God did not say “I was the God of Abraham et al.” or “I will be the God of Abraham et al.” but I am the God of Abrhahm et al. If this argument holds then those who have gone before count as living, at least by this commentators argument, though they may not meet your breathing criterion.
Roman Catholics don't seem to read the Bible much. But when they do, they pluck lines out of context and try to use them to bolster some errant philosophy or ritual. Like Mary being the new Eve.
And now because God said He is the God of Abraham that is supposed to be the evidence which permits us to violate the Second Commandment and bow down and serve and pray to statues of dead people???
Wake up, Rome. "Flee from idolatry."
