'Religion' in the Bible

But this I will say openly to you, that I do give worship to the God of our fathers after that Way, which to them is not the true religion: but I have belief in all the things which are in the law and in the books of the prophets:

Instead they had some disagreements with him about their own religion and about a certain Jesus, a dead man Paul claimed to be alive.

Which knew me from the beginning, if they would testify, that after the most straitest sect of our religion I lived a Pharisee.

But we have a desire to give hearing to your opinion: for as to this form of religion, we have knowledge that in all places it is attacked.
