Oh, I see. You think you are the arbiter of faith by judging practice. Got it. Sinner.
Actions speak louder than words.
It’s what a person does that shows what they really belive, not what they say.
So yes, it is reasonable to judge by someone’s practices.
Indeed I am a sinner, I sin daily.But I have a Savior that has paid the price I should pay, He lived the perfect life I should live,and imputed that righteousness to me ..Praise the Lord .. that Savior tells me to beware of false christs
Mat 24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
Mat 24:11 And many false prophets shall rise, and shall deceive many.
The roman christ saves no one..
Correction, judged by scripture. The Catholic Church stands condemned.
