Fred Clark has a post on his blog focused on the requirement to accept Gentiles communicated in Acts 10-11, as God is described as expanding his people to include those previously excluded. In that connection he writes:
I believe that denying LGBT people full legal equality is objectively immoral. I believe that excluding LGBT people from full inclusion, full participation and full equality in the church is objectively immoral — and objectively unbiblical….It’s particularly astonishing that the very same American Christians now excluding LGBT Christians from full inclusion and full participation in the church are, overwhelmingly, Gentiles. We Gentile Christians would, ourselves, be excluded if it were not for that lesson Peter learned in Acts 10:1-11:18. Freely you have received, freely give. For the measure you give will be the measure you get back.
