Dr. Eckleburg to Petronski
No church uses the "Institutes of the Christian Religion" as dogma of its faith.
It's one book written by one man.
Unlike the catechism of the RCC which all Catholics are required to believe.
And as pointed out, the RCC catechism is over 200 pages longer than the Bible itself.
Sounds funnier every time I type it.
Get the difference?
Got it. When you agree with Calvin, et al, they are “authoritative,” when you don’t they are just “one man.”
