re: Why have churches started allowing gay preachers?

You’re half right about me being wrong. The older brother was her husband and struck down for being wicked. Genesis 38 8-10 specifically mentions what Onan did and why he did: too keep from impregnating her because the child would not be his. That was what got him into trouble. The whole story is a fascinating window into that culture. The dad ends up inadvertently restoring his son’s line because she disguised herself as a prostitute and seduced him. The dad did not pull out.
