>Why is it that natural law mandates that every single sexual act be open to life?
Rome teaches this, not necessarily Scripture, which matter far more on these matters than Rome, Aquinas, Augustine, etc.
>Why this and not the Orthodox view that procreation is an essential purpose of marriage but that every act need not necessarily be open to life?
I'm not sure about the Orthodox view, but it should be clear from the Genesis onward, including Song of Songs, which does not reference procreation, that our sexual nature and the sexual act comes from begin the image of God first and foremost, not for a purpose of procreation as important as that is.

>Priests can only repeat ad verbatim ad naseum Catholic catechistics instead of the Bible, other theologians, etc.
I'm not surprised OP, you should seriously consider a different church that respects God's wisdom found in His Word, like Reformed Baptism.
>The idea that a husband and wife performing non-procreative acts on each other will send them to hell is simply laughable to me.
If God finds it laughable by adding the Song of Songs, then you should as well. Worse, these men, by preaching against the marriage is honorable to all and the martial bed that IS undefiled (not should be as Heb 13:4 is commonly translated), they teach doctrines of demons, see 1 Tim. 4:1-4.
> No amount of esoteric philosophizing and JP2 Theology of the Body can change the fact that this comes across as far too obsessed with the physical nature of the act itself and reduces it to its mere mechanics with little regard for the actual circumstances of the couple
See above about the image of God. A couple should focus on each other's pleasure and well-being because that's what each person in the Trinity does. The Trinitarian Person delights in the other, see for example the baptism of Christ where the Father says He is well-please in the Son or Prov. 8:30 as Wisdom might refer to the Son or the Spirit. Just as the delight of the Trinity figured in the world's creation so to does a couple delight, God willing, occasionally result in children.
>I want to believe in the doctrines of the church
Maybe God is giving you the hint your "church" (I'm assuming you are Catholic) is demonic with sexuality as well as more important matters and 'you need to flee ASAP.'
>A simple blanket ban rather than a more nuanced approach comes across as taking the easy way out and not wanting to admit that the church has been misguided in some of its teachings on sex in the past (e.g. Augustine and Jerome)
Oh boy, when researching sexuality and eschatology, I learned a lot on the church fathers and their views on sexuality. Sadly, the pagans and atheists reasonably make fun of us (though they themselves are evil) on this issue because these "fathers", right in many areas, were severely wrong when it came to marriage and sex, being influence by the sodomite Plato or the proto-rationalist Aristotle.
>thank you.
You're welcome! If this post disappears after you have read it, it's because mods are not too happy with my criticisms against them, but's that's another issue I hope can be settled soon.
