No problem. This reminds me of when my old church visited another, older, more traditional church for second service. My pastor brought the choir and the band. Our keyboardist couldn't make it so it was just me (the guitarist), the bassist, and the drummer. As we were getting set up, someone in the host church's leadership pulled me aside, with the guitar strapped to my back, and asked when is our musician going to come. Lol! Based on that convo and a few other things said, apparently you're chopped liver at that church when you're instrument isn't the piano!
IMO, you have a couple of options:
- Conform. Only do hymns. If they start to show interest in branching out, see if you can coordinate with the preacher on making little changes. If you're being paid, this is the recommended course of action.
- Step Down. If he's truly callous, and you don't care to put up with that treatment, step down. If he believes you're not a fit, he should find a fit. Without hearing my tone, this may come off as spiteful or petty, but it's not. When you step down focus on honoring God and He will direct your path.
Whatever you choose, do it prayerfully, and graciously.
