Hail,
As a student, these were questions which often plagued my mind. As a student, we’re obliged to
ask why. So I did. The answer played a major factor into bringing me into the CC. It has been a bit bothersome, at times, since I’m still somewhat influenced by Protestant teachings.
I worry that if my cup is full of bad water, would that water contaminate the good water? I’ve been mostly trying to throw away that bad water, so there is none of its foulness left.

But it’s hard, because the water sticks to the cup and brings with it doubt and insecurity. How can I join Catholicism like this?
It’s not good. Not good at all.
