As long as you don’t challenge their basic assumptions, it’s as easy to get along with Baptists, as it is to get along with anybody else. That’s just Human Nature 101.
Unless it were some extraordinary circumstances, such as a generic non-denominational service in a situation where Catholic Mass is unavailable (such as a hospital or, perish the thought, a prison), I couldn’t recommend attending non-Catholic worship services as a substitute for Mass. And above all, don’t partake of their communion service. In my part of the country, it’s not unusual for truck stops to host non-denominational Christian worship on Sunday. Never attended (I’m not a trucker), but I wouldn’t have any serious objection to it, if that were my only alternative for keeping the Lord’s Day holy.
