Where did you get the notion that Catholics worship St. Peter? St. Peter declared himself unworthy of dying like Jesus, but never shied from dying for Jesus.
Peace be with you
I was raised Catholic. Of course, Catholics don’t use the word ‘worship’, but when the nuns, priests, and dogmas of the religion tell you to pray to the dead ‘saints’, and elevate creatures made in God’s image as something more than mere mortals, I call a spade a spade. That’s worship.
