You seem to believe you need to read the same verses of Scripture more than once...
Our Lord Jesus Christ said to “eat this bread” and “drink this cup” in memory of Him. Did He mean only once?
Lets not talk past each other, many needless arguments begin that way. I was speaking of accepting Jesus Christ as your Lord and Savior, you are speaking of Communion, the wafer and the wine. At least from a Protestant POV, those two things are not (always) the same.
Catholicism did not always have a literate population of believers or supplies of printed Bibles for the masses. There are many ways to learn about God and His teachings.
