No, Matthew. It’s not evolution itself that has ruined the faith of millions. It’s finding out that what their churches were teaching them about it was simply not true. Pastors and church leaders are in a position of trust, and teaching things that aren’t true is a breach of that trust. It is that breach of trust, and not evolution itself, that undermines young Christians’ faith. This is why you need to know what you are talking about before you try to challenge complex technical subjects.
As for BioLogos, they constantly get testimonies from Christians who have managed to hold onto, restabilise and re-establish their faith after having ended up in such a situation.
