Basing the answer from the Bible, religion is a way of worshipping God or a deity or serving God or a deity. The Bible also teaches us true religion and true worship or true service to God. In the book of James 1:26, it says;
If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion is vain.
We are made to understand that if you do not bridle your tongue, the way you speak. If you speak carelessly, or speak with hatred or speak bad things against people, then your religion is in vain. In other words, there is a good religion and a vain religion, the true religion is taught in the church of God.
1 Timothy 3:15;
if I am delayed, you will know how people ought to conduct themselves in God's household, which is the church of the living God, the pillar and foundation of the truth.
This is where men are instructed on the right thing to do, all the teachings are on how to behave, how to worship, how to serve, how to walk, how to live, how to deal with people are all taught in the church of God in the Bible.
Remember that religion is worshipping God, and how do we worship? Let us read John 4:23-24;
[23] But the hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth, for such the Father seeks to worship him. [24] God is spirit, and those who worship him must worship in spirit and truth.
It is very clear that the religion taught in the church of God is to worship the father, God, in Spirit and in Truth, this is the True worship.
If you worship an animal or a snake or a bird, or images, you are not worshipping the True God of the Bible, you are worshipping a false god. And that is something that God hates; idolatry, something very evil in the sight of God.
Romans 1:25;
They exchanged the truth about God for a lie, and worshiped and served created things rather than the Creator—who is forever praised.
Worshipping the creature and not God is a lie, we must worship the Creator and not the creature.
Romans 1:23;
23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
Anyone who does these things belong to a false or erroneous religion because the only True religion and True worship, is to worship only the Creator.

We should worship the creator not the creature.
We should bridle our tongue because for anyone who speaks carelessly or with hatred, his religion is in vain.
Religion is the mode of worship which person take as their God.
