In situations where topics come up and I am pretty sure my thoughts either 1) can’t be expressed with the appropriate nuance or justification in a couple sentences or 2) are likely to be misunderstood and judged or 3) are different than what my present company assumes is the default Evangelical position (and my origins views would meet all three of those criteria), than I usually ask myself why I want to say something.
If my reasons for speaking up are essentially selfish or less than honorable (I want to feel validated or vindicated in some way, I want to put someone else in their place because I think they are being an arrogant jerk, I want to be right, etc.) than I try to keep my mouth shut. But if I am with people that I have a close relationship with and I feel like something someone has said is hurting their Christian witness because it is blatantly racist, sexist, anti-poor people, homophobic, xenophobic, or anti-science, I am more likely to spend my social capital and reveal my potentially unpopular thoughts on an issue. In those cases I feel it is a matter of integrity and justice to address the issue. It’s kind of rare that anti-science attitudes rise to the level of what I would call sinful though, or maybe I just care more about gender, race, and poverty-related issues, so I am more willing to risk my reputation as a respectable Christian woman over them.
If people ask me directly about what I think about Genesis or young earth creationism, I’ll tell them. But I definitely don’t delve right in just because someone else states their view or the topic is being discussed around me, especially if I think it would derail the real purpose of a class/meeting/discussion.
If I were looking for a church, I would look for one where people were getting off their butts doing things to make the world a better place in Jesus’ name, where the leadership was humble and open to learning and didn’t think they had everything all figured out, and where I sensed people were accepted and appreciated and pushed to be more Christ-like even if they disagreed on minor points of doctrine or Christian lifestyle choices. I would not make “agreeing with my views on origins” a deciding factor, though if they were militantly YEC that would be a red flag and probably a deal breaker. I have never gone to a church where I agreed with the church’s official position on everything, and it hasn’t usually been that painful.
