Your donation would be treated no different than a donation to any other charity. Give unto Caesar what is owed to him so that your payment to your spouse is not reduced. Donation to charities are secondary to alimony.

If you took it to court I think your payments would be reduced if your income was reduced.

This is not a Church and State issue. Christians don't get special privileges. We should treat others as we would like to be treated.

Church and State need to be separated because the only solution for the State is its destructions which is coming in the Great Tribulation. But the Church will not be destroyed.

It's like our flesh. Our flesh can't be fixed or refined. The only verdict is death. Hence, the solution is to die on the cross with Christ in co-death. Amen.
