They will have a serious problem trying to re-write what is written as “Father”. Here’s just a sampling....
“Father, I want those you have given me to be with me where I am, and to see my glory, the glory you have given me because you loved me before the creation of the world.”
John 17:24
See what great love the Father has lavished on us, that we should be called children of God! Psalm 103:13
But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you.
Matthew 6:6
Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?
Matthew 6:26
Do not love the world or anything in the world. If anyone loves the world, love for the Father is not in them.
1 John 2:15
Yeah, I think they did not read that last passage you cited too closely...
