I’m with you. I’ll go even further.
Folks are going to hate me for this, but I think it’s more than just immodesty. I think it’s dangerous.
Christian marriage is selfless. It asks “How can I reflect Christ to [my spouse]?”
What I see described in these videos has the danger of reducing Christ to a mere component of their cultural identity, a nice set of sometimes-useful rules (like Lists) that can help with practical things – the ‘religious’ side of Christianity, if you will, absent the ‘faith’ which gives it meaning. This can lead to a glory of Self over Christ (and Spouse, should they ever stumble off their pre-nuptial list). Even the medium used to deliver the messages seems to reflect this, with flashy, movie-quality effects and theatrical story lines focusing on ‘me’ getting ‘what I always wanted’ from what might actually be one’s personal false god (a good test of who’s actually being worshiped is to replace ‘God’ with ‘Fairy Godmother.’ If the meaning fits, you might be promulgating Joel Osteen’s sort of heresy). Instead of the Christian question, the question asked appears to be “How can I feel [more Christian] about myself?” as if Christianity were a culture or mode of earthly empowerment. One needn’t be Christian to misplace the attention here; anything could fill those brackets.
Again, not saying that this is the way every person who makes lists will go. Just acknowledging that when we stop seeking ways to sacrifice, we start looking for ways to keep track of wrongs. Christian marriage is for those wishing to sacrifice, not for those seeking someone worthy of sacrificing for.
