"Let no one eat or drink of your Eucharist unless they have been baptized … If any one is holy, let him come; if any one is not so, let him repent." Repentance normally involved confession of one's sins: "receive the Eucharist after having confessed your transgressions, that your sacrifice may be pure."

I was looking for the pictures found in the catacombs that show the Early church worship before Christianity was legalized . Ill post them when i find them
