I was raised in the Roman Catholic church. Within that church, we had local churches called parishes within a diocese. I was very involved, and the same basic families in our local community were a part of my church upbringing.
When I was in college, I attended a church in the home, and learned a lot of the Bible. One thing I learned was that a “church” was not a building or even a denomination. It was the “called out” of God.
