I read that. That’s pretty cool. The LCMS doesn’t even believe in the Big Bang Theory.
I've mentioned this before I think when we've spoken. But a year ago I jointed a local AALC congregation, which is in altar and pulpit fellowship with the LCMS. The official position of the AALC, like the LCMS, is YEC. One of the pastors (not active, but retired, but who was serving as interrim pastor until we received our current active pastor) and I have had chats about science. He has had no problem talking about science and recognizing science. We geeked out a little talking about dinosaurs one time after Mass in the fellowship hall.
What I'm getting at is that boots-on-the-ground, Lutherans--laity and clergy alike--are much more diverse than what official upper eschelon denominational positions might suggest. While pastors are more strongly bound, due to their committments, laity are not under the same kind of expectation.
Before joining the AALC I was ELCA, which I certainly had more agreements with on some social issues and their more open stance on science. My reasons for becoming AALC rather than remaining ELCA didn't come down to politics or science; but confessionalism.
I'm not going to say that I don't still have reservations about my new church. I absolutely adore my church. But I sometimes worry about external influences affecting things.
But I have to realize that "the perfect church" doesn't exist. It's not about me.
At the end of the day here is what I'm saying: I don't think you should leave the LCMS/become RCC because of different views on science. That should be one of the least important things. If you are, based upon conscience, convinced in the intrinsic truth of what Catholicism confesses (in where it differs from Lutheranism), then you should follow conscience. But if the reason is purely over a peripheral issue, like the LCMS officially rejects evolution/old universe/big bang/etc then I want to reassure you that it shouldn't be a huge concern.
There are lots of people in the LCMS who accept science as science.
The core questions I hope you are asking yourself are what do you believe about God--about the Gospel, and about how you should treat your neighbor. The things that truly matter as a Christian. Our ideas about science, and in a lot of cases politics, should only really become a matter when it affects our confessional and vocational life--who we are as a people that calls Jesus Lord, tasked with the privilege of representing Him through love toward others, and holding firm to the gift and promise of God's grace toward us which saves us, keeps us, and comforts us with His love.
