Peter was not and is not the foundation for the church.
The Romans who killed Peter say he was.
The pagan Romans who crucified Jesus said he was.
The current pagan Romans say he was.
Start believing the bible instead of Romans.
1 Corinthians 3:11
For no other foundation can anyone lay than that which is laid, which is Jesus Christ.
Same day he named him Petros.
And same day he said "You are Petros, and upon this petra will I build my church."
Petros: masculine word, name for a man.
petra: feminine word, name for a pebble, rock, or a cliff.
What was the petra Jesus talked about?
Jesus: And whom do you say I am?
Petros: You are the Christ, the Son of the living God.
That is the petra. That Jesus is the Christ, the Messiah, the Son of the living God. Upon that foundation is the church built, and upon no other.
satan is an adversary, not a proper name.
anyone who is your adversary, is your satan.
And the devil is certainly your adversary, and is most often called "satan".
Lucifer is a crappy latin translation of Heylel ben Shachar, Shining One, Son of the Morning.
i.e., an angel.
the devil was created as an angel, and not as a "light bearer" or "light bringer".
