“And if marriage is “only” God’s concession to us... is the marriage of Christ to the church also “only” a concession?”
No, but that is a perfect relationship that our marriages can only ever hope to be a shadow of.
“The point is, to everybody looking at this question: be sure it is God’s individual calling, not your own personal hurled cynic’s ban.”
Why? Why can I not look objectively at the state of things and honestly say that marriage nowadays is a sham that I want no part of? You call that cynical, but I call that rational.
Because you are mixing the world into a test tube that should not have the world in it. That’s why.
