Potentially, very. There are some example of abuse of religion, else unknowing abuse; while some are genuine, yet still a little selfish (if you are genuine in your mission and gain loads of cash, then you would give it away to charity, wouldn't you?). Here are some examples whereby you can make decent money from religion. Others should feel free to add more; but please do not remove.
I hope these examples will be proof enough that you can make money from religion; but if you have the intention of doing so, most people would condemn you for your actions because you have acted in your own interests, not in the service of God. (Note that it is a similar story with religions other than Christianity, but Christianity is quite possibly the richest (don't quote me!))
Therefore, religion is lucrative, but this should not be what you have in mind; instead you must feel that you are serving God through your actions, and put your own benefits last.
