I was raised Catholic, fell away from the faith, then came back as an Evangelical... but getting involved in my local Catholic Church... I remember reading Lewis- Mere Christianity while my friend was reading Surprise by Truth!
I asked him what his book was about, and he said people converting to the Catholic Church... I was like who in their right mind would do that... He suggested Rome Sweet Home... and the rest is pretty much History!
Welcome back. I'm sorry you ever had to leave.
