The Lion of Judah was a symbol used by the Israelite Tribe of Judah.
The “Lion of Judah” is another name for the Lord in the bible. 
It’s not a religion but a name for God found in the Christian Scriptures.
The lion of Judah refers to Jesus when he comes back for the end times.

When I imagined what the Garden of Eden would look like, I saw a Lion Tree, a tree with the face of a lion. The swirls in the night are stars.
 
Job 33:15
“He speaks in dreams, in visions of the night, when deep sleep falls on people as they lie in their beds.”
