OP, the only Catholic person on my Facebook friends list is my midwife, and the only reason I even knew she was Catholic was by her posts there (even though I saw her in person many times, obviously, and she is a wonderful person to be around). She posts a lot of memes with inspirational quotes from the Pope or other respected leaders. She posts about her struggles and her answered prayers. She comes off as very genuine and approachable concerning her faith. And I will tell you, it does pay off-when we decided to attend our first Mass, I messaged her for advice. And now that we are joining the church, she is going to sponsor my daughter at her baptism, which is so beautiful too because she also delivered her!
I have to be honest, your list would’ve sent me running for the hills. But shrouds and ghosts and demons kind of freak me out, so…it might be appealing for some, but for me, I’d rather see the quotes and memes that encourage the faithful to greater holiness.
