Rather, let us just say that they are lost and it is up to Christians to find them and bring them back to Christ.
While that is true that we are called to find them and bring them back to Christ, it is also true that there are none so blind as those who will not see.
So many of the “christians” pick and choose what to belive and cherry pick parts of verses to support their beliefs, cling to it with a death grip and damn anyone who doesn’t agree. We’ve certainly seen alot of that.
Before someone gets their knickers in a twist, that’s not to say that there aren’t Catholics who line up at the cafeteria and behave in a similar manner.
I think it is unfair for you to lump all Catholics into one group - "...they are lost". Some Catholics are mighty fine Christians.
