Religion is of man. Jesus made this point many times and voiced his displeasure with "religion".
"Religion" and/or "Religious" in the New Testament:
2 Tim 3
1
But understand this: there will be terrifying times in the last days.
2
People will be self-centered and lovers of money, proud, haughty, abusive, disobedient to their parents, ungrateful, irreligious,
3
callous, implacable, slanderous, licentious, brutal, hating what is good,
4
traitors, reckless, conceited, lovers of pleasure rather than lovers of God,
5
as they make a pretense of religion but deny its power. Reject them.
1 Tim 6
1 Those who are under the yoke of slavery must regard their masters as worthy of full respect, so that the name of God and our teaching may not suffer abuse.
2
Those whose masters are believers must not take advantage of them because they are brothers but must give better service because those who will profit from their work are believers and are beloved.
3
Whoever teaches something different and does not agree with the sound words of our Lord Jesus Christ and the religious teaching
4
is conceited, understanding nothing, and has a morbid disposition for arguments and verbal disputes. From these come envy, rivalry, insults, evil suspicions,
5
and mutual friction among people with corrupted minds, who are deprived of the truth, supposing religion to be a means of gain.
6
Indeed, religion with contentment is a great gain.
