look up any word, like pussy:
 
1.
A Christian who is the exact opposite of a "Sunday Christian." A ChristFanatic, is a Christian who is very passionate about their relationship with Christ. They are not ashamed of what they believe in. No matter what the world say or does, a ChristFanatic is determined to live for Christ and share the good news!

A ChristFanatic is far from perfect, but God's awesome Grace keeps He/She up and going everyday.
That guy Luke is the definition of a ChristFanatic!
