WORLD Magazine posted a list of twenty things that your local gathering can do to become more adoption-friendly. I think it is a good list, especially these points:
9. Encourage the church family to give financially to adoptive couples. Giving financially to adoptive parents is one of the most—if not the most—significant things you can do. As potential couples take the giant step of faith in the adoption process, one of the biggest concerns will be "how are we going to pay for this"? A monetary gift along with a note of encouragement can greatly encourage the couple by affirming their decision to pursue adoption.
10. Create a standing church fund for adoptions costs. Church members can contribute to this special fund that adoptive families can utilize (either an interest-free loan or one-time gifts to these couples). Churches can also take up a special Deacons' Fund offering.
The church should be very cautious to spend it's monetary resources first and foremost on those things we are explicitly called to do before we spend on stuff we are not called to do.
