... faith and reason are not opposites. They're different things. They don't apply to the same issues, don't work the same way, etc., so forth, and so on. They handle different epistemological problems. Basic faith claims, of the not-yet-justified sort, are also absolutely vital is such things as freaking science. You don't get to just throw faith out the window or ignore its impact and importance, nor downplay the interaction between it and other things (like reason and logic) in regards to religious beliefs. It's not a simple subject and it can't really be boiled down to something pithy.
You're welcome to state that you can't believe in something that has no basis in reason and still support reason, but in regards to a christian belief discussion, you are doing so in explicit contradiction to literally centuries of christian theology working to integrate the two. Huge swaths of the church has disagreed with your position over the years. From outright stating that the christian position is the rational one, to holding that faith and reason can stand side by side, and all sorts of related variation, christian theology and belief have a tremendous interrelation with reason and rational thought. There's a reason the relation between faith and knowledge, and exactly what faith is, is the subject it is in the fields of theology and more general religious thought. It's a tremendous freaking deal.
You're also incredibly misrepresenting things when you note christian opposition to science without mentioning christian support of science, which is very, very much a thing.
I mean, I get it, you're running of the (oft times living, to be fair) caricatures of extremist christian thought, but one of the bloody important things to remember about that is that isn't all of it. To a darn fair extreme, it's not even a notable fraction. There's a tremendous depth and breadth to christian beliefs, for all that there's some vocal schlubs out there nowadays doing their damnedest to shit all over the more nuanced parts of them.
