Is "The Church" capitilized?

For example, if I am saying "He gained money for The Church" is that capitalized? I know it is capitalized when it is a proper noun (ex. St Patrick's Church), and I know that it is lowercase when used in a simple sentence (ex. I went to church). However, I'm not sure if "The Church" is capitalized- with the word THE in front of it. All answers are appreciated.
