the divine ignorance (and friends)
I think you might have answered a lot of the issues you have with those who believe in other denominations.
Something resonated ... and so you find a home in the church. It's the same for many, and for many more, the place in which they find themselves by birth or whatever was always adequate, so there was no need to question nor seek elsewhere, something resonated.
I left the church in my late teens, and joined a cult when something resonated. I left that a decade later, and happened upon a book of essays on the Sophia Perennis and boy, did something resonate then! That pointed me towards Greek metaphysics (essentially Platonism) and thence to the writings of the Fathers, and something resonated...
And so it goes.
Indeed it does. As an observer and a believer, I would definitely say that God had a hand in your spiritual development. And yet, he let you make your decisions, whether good or bad, and worked all of it toward your good. He did not not need to circumvent your path at any time in order to prove himself right, or win an argument. If this is true, why should it be any different for Wil? Or for me, for that matter. He is able to love without interjecting himself too forcefully into a life, because he takes great care with what he is creating.
You also wrote, concerning Unity, that it is a religion without obligation. I would say rather that it is a religion without much pressure or threat. Obligation can also be a matter of conscience. In other words, it depends on how seriously the hearer takes the exhortation. If he takes it seriously (it resonates), it will produce action as the person will expend effort in order to put it into practice. This is the struggle that I would not circumvent through zealous yet untimely intervention. God meets us where we are, not where others believe we should be.
