I think it is probably necessary - in this era - for serious Christian churches to avoid all Good Works.
It's just one of those things that we can't really afford to get involved in. Good Works are the temptation and mainstream sin of our age, all the trends and pressures are in that direction and it is too likely to be swept away sooner or later.
For a serious Christian church to get involved in Good Works is like an ex binge alcoholic trying to drink moderately with his old boon companions on a daily basis.
