The pastor gave a sermon on Galatians, which was the typical sermon on Galatians for the most part (and believe me, I’ve had plenty of experience struggling with that epistle).
He did say a few different things though. The first was that he and his wife adopted three sisters, which I thought was terrific. So many of the opponents of Christianity, particularly those who are “pro-choice” complain that while Christians want to save lives from being aborted in the womb, we don’t care about what happens to kids afterwards. Adoption is one of the ways to care for kids afterwards.
The other thing he said had to do with identity, and yes, he brought up (among other things) gender identity. Of course he also brought up law vs. grace as if non-Jews could ever have been “under the law” in the first place, but I set that aside because I’m way past arguing about it.
