In vain do these people worship me teaching the doctrines and traditions of men.
‘But in vain do they worship Me, Teaching as doctrines the precepts of men.’”
Matt 15:9
I tried to write my own Bible, but it didn't come out too good. Why don't you get a pair of scissors and cut out verses of scripture out of your Douay Rheims.
7 Hypocrites, well hath Isaias prophesied of you, saying:
8 This people honoureth me with their lips: but their heart is far from me.
9 And in vain do they worship me, teaching doctrines and commandments of men.
I'm using your Bible! Does your bible say that if you add to the Word of God then your worship is in vain?
3 If any man teach otherwise, and consent not to the sound words of our Lord Jesus Christ, and to that doctrine which is according to godliness,
4 He is proud, knowing nothing, but sick about questions and strifes of words; from which arise envies, contentions, blasphemies, evil suspicions,
5 Conflicts of men corrupted in mind, and who are destitute of the truth, supposing gain to be godliness. 1 tim 6
They are conceited; knowing nothing. They come out with their controversial questions: Christians can't have demons, that's sinless perfection, you can't be full of the Spirit of God and the spirit of the Devil. You read in Revelation where Babylon is a dwelling place of demons, because the stain glass windows did not keep them out.
