Charity donation is tax free as well. 呵呵

So please donate as much as you can.

Glad you can see the worldly benefits (to the society) of Christianality. But this worldly benefits (to or from)Christians are from heaven, not from their own effort. So no true christian will claim the credits.

A lot of comments here are purely from worldly view, so they are not about Christianality as a faith at all. At most, it is about cultures influenced by Christianality.
