For a while in the mid-1990s I was seriously annoyed with Reformed Christianity. I agreed with the theology, I just found it to be presented with a consistent and overwhelming arrogance - actively disdainful of other Christian traditions. And this even when the proponent disagreed with many of its central elements (tossing out at least 2 of the TULIP letters).
In retrospect, the issues were mine as much as the church we were attending, but I still always get a pleasant little smirk on Easter Sunday when the entire (more or less) Protestant world is indebted to the hymnody of Charles Wesley. To me, this one of the two central liturgical pillars of Easter worship (the other being a call and response of "He is risen - He is risen, indeed" - which I taught to one of my 5 year olds, though she was reluctant to do it in front of others).
Enjoy the irony, but more importantly, enjoy the worship of the Living God.
