Just to reiterate what GH31 and 25 have said, RetroV is not a hit-you-over-the-head-with-a-Bible experience. I can understand your reluctance since most church-affiliated activities can be a bit heavy-handed, but I've read everything I could find on RetroV and the participants come from all areas of belief and non-belief and all say there is nothing they found objectionable about the content. I am very spiritual but not at all religious, so I did look into that aspect of RetroV out of curiousity and I found nothing of concern at all. As mentioned there is a prayer here and there and the God component of marriage is discussed, but mostly it's couples-focused.
