Sure everyone is.
The problem is, all the made up stuff of Catholicism isn’t going to do anyone a lick of good.
God revealed to us in Scripture what mankind needs for salvation. People certainly are free to exchange that for the doctrines of men, to the peril of their soul.
If you wish to put the catechism ahead of Scripture, it’s your prerogative.
But you can’t say you weren’t told.
Get back to me when some Catholics come to your church and try to force you to believe what we believe.
