So what? Most types of successful breeding, nurturing relationships found in human society exist outside christianity, so secularization is no threat to ongoing existence of breeding and nurturing in human society, it's just a threat to christianity.
On the other hand, long term postponement of humanity's extinction can only grow out of extended and unremitting scientific and technological advancements. Scientific advancement is incompatible with any society that takes christianity seriously.
So secularization is no threat to the fundamental reason why marriage exists - humanity doesn't go extinct - but it is a threat to christianity. Christianity, on the other hand, is a threat to the fundamental reason why marriage exist, even if it uses perverted reasoning to uphold some particular form of that institution. So christianity is incompatible with marriage, if one take marriage for what its ultimate purpose really is.
