The Catholic god shows no mercy. All remission of sins has to be earned. That's not mercy, that's subjection.
Sounds like it borrows heavily from Islam
Evidently, you have not heard of the Divine Mercy chaplet, Evidently, you know next to nothing about Catholics.
“The Catholic god shows no mercy.” What a piece of junk!
The Catechism of the Catholic church claims they worship the same God.
For that matter, Islam began shortly after the Catholic church was established, well before the Protestant Reformation.
