Religion

♦Christianity is, to those that truly believe, a lifestyle.
Religion is belief in a deity or god.
Christianity is belief in the One True God, The I Am, Jehovah.

There are religious spirits, however.
Religious Spirits are demons that cause people to be so religious that they are self righteous and too good to do certain things. It can also be connected to things that are meant for idol worship.

Catholicism is a religious spirit(that's another topic).
Religious spirits can come through shrines of Mary and baby Jesus and shrines or alters of any kind (idolatry).
Rosaries bring religious spirits.
Stain glasses windows with various images are demonic as well.

James 1:23-27 KJV

For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass: [24] For he beholdeth himself, and goeth his way, and straightway forgetteth what manner of man he was. [25] But whoso looketh into the perfect law of liberty, and continueth therein , he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed. [26] 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. [27] Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.
