It’s not just Mary, but the Pope, the Deuterocanon, Purgatory, Intercession by Saints, the
idea that you need to confess to a priest, (granted maybe a little of bad events in history),
Transubstantiation, Apostolic Succession (technically same as Pope), TRADITION (yikes
the Protestants loathe “Tradition” !!!), and so many other things.
The Good Shepherd knows when it is safe to let his fold graze in
the open field, when the wolves are gone,but if some sheep want
to run off and do their own thing, that is their choice to regret.
When they had finished eating , Jesus said to Simon Peter , “Simon son of John, do you love me more than these ?”
“Yes, Lord,” he said, “you know that I love you.” Jesus said, “Feed my lambs.”Again Jesus said, “Simon son of John,
do you love me?” He answered, “Yes, Lord, you know that I love you.” Jesus said, “Take care of my sheep.”The third
time he said to him, “Simon son of John, do you love me ?” Peter was hurt because Jesus asked him the third time,
“Do you love me?” He said, “Lord, you know all things; you know that I love you.” Jesus said, “Feed my sheep. Very
truly I tell you , when you were younger you dressed yourself and went where you wanted; but when you are old you
will stretch out your hands, and someone else will dress you and lead you where you do not want to go.” Jesus said
this to indicate the kind of death by which Peter would glorify God. Then he said to him, “Follow me!”
-(John 21:15-19)
