Chris Hackett and support for abortion

Chris Hackett belongs to a church that supports abortion. In fact he was the treasurer of that church. Does the Hack support his church or does he support the Bible? If he supports the Biblical understanding of “Thou Shalt Not Kill” in regards to Abortion then why did he serve as an officer of a Pro-Abortion Church? If he does not care enough to know what his church teaches, preaches and confesses then can we trust him in Congress?
