In John 1:18, it seems no one has seen God's face:
No one has ever seen God, but the one and only Son, who is himself God and is in closest relationship with the Father, has made him known.
And in Exodus 33:20, it is also mentioned that you cannot see God's face as you will die if you see his face.
"But," he said, "you cannot see my face, for no one may see me and live."
Now we know that it is impossible to see God's face as you won't live after it, but somehow Moses saw his face and lived. Exodus 33:11:
The Lord would speak to Moses face to face, as one speaks to a friend. Then Moses would return to the camp, but his young aide Joshua son of Nun did not leave the tent.
So did Aaron, Nadab, Abihu and the seventy elders of Israel. Exodus 24:9-11:
Moses and Aaron, Nadab and Abihu, and the seventy elders of Israel went up 10 and saw the God of Israel. Under his feet was something like a pavement made of lapis lazuli, as bright blue as the sky. 11 But God did not raise his hand against these leaders of the Israelites; they saw God, and they ate and drank.
Oh, and Abram too. Genesis 12:7:
Then the Lord appeared to Abram and said, “To your descendants I will give this land.” And there he built an altar to the Lord, who had appeared to him.
According to the Catholic Church, how did these people see God's face and live even though he clearly says no one can see his face and live?
