it is just unnecessary, unneeded
If I love someone, I want to know her family. I love Jesus and I want to know about His saints. Neither is "necessary"
I know the big ones. I know the current one.
Protestant communities of faith don't' know much about the Catholic Church, and what their pastors do know they lie about.
“Protestant Churches(fxd) don’t know much about the Catholic Church, and...”
...vice versa. I also do not know much about Presbyterians, Lutherans or Orthodox faiths but I am hoping to learn w/o calling their leaders “liars.”
