Prior to having our marriage blessed at St. Paul the Apostle Church in Los Angeles, I attended catechism. I don't remember much about the instruction except that one does not question the word of God and I had a lot of questions. Accepting beliefs on faith alone was not something I was accustomed to, nor could I easily accept. Fortunately, the Paulist Father blessed the marriage. Most of the time when my wife attended mass on Sunday’s I went with her although I never converted to Catholicism.
My wife and I are Godparents to my older sisters firstborn daughter. I was Christian but no longer Catholic albeit eternally Cashew and so my friend Father Mike at the diocese said he had no problem with us being Godparents.
And I still can't recall "The Apostle's Creed".

But God cares not for rote, holy or rolly.

How do I, an Atheist know this? The Nazarene spoke on it. Most denominations (and all mooslimes) ignore His truths.
