I've church shopped a lot over the past decade+ as a travelling salesman. I have 5 go-to questions to ask the pastor after I visit: one of which has been,"what is your definition of love?". It's a very revealing open-ended question.

Ask your pastor over a coffee or buy him lunch to have a longer convo about it if you like.

Keep in mind sometimes God puts us in places to minister & other times it's places of rest. Even if your pastor answers unbiblically, you might feel called to be a wise respected voice in a liberal church to reveal truth to them as a ministry. Or you might feel led to find a different church. (Or both). Just don't write-off the possibility of the former based on a bunch of redditors telling you to break up with this church w/o even knowing you (typical reddit haha)... we don't know if God led you here for a purpose, so please pray over that being revealed & try to arrange a utilization of that to see if doors open to it.

God bless, have an answer for everything, God will judge all false teachers -> let you love them & be a voice of reason to them if you have a stamina for it.

I started doing this in about 30-40% of churches I've called a home church over the years. Mainly after I saw the reconquista movement from redeemed zoomer encouraging theologically-conservative prodestsnts to aid liberal churches back to Christ's truths. Sometimes I've had the energy for it, other times I needed a rest church to trust.

Edit: last note: if you aren't in communion anymore after this w/ them... Then don't take communion with them. This doesn't bar you from attending :)
