That's stupid beyond belief....don't you think that Jesus ever referred to Joseph as Father??????get real, Father is a normal word and used by everybody.
I will be 72 soon and I have never heard anyone refer to their dad as father. It was always Dad, Pops, Pa, etc. I called my dad Pa since that is what my oldest nephew called him. I am 2 years older than he. Even my great granddaughters refer to him as Pa. They were born years after his death but we all talk about my parents. They have seen pictures of them, too.
