Yeah, that is what I grew up with as well. If I knew about lectionary, I'm sure I assumed it was just a Catholic thing. I've come to be a big fan of lectionary, though. It forces you to deal with more than just the stuff that you like and which is easy for you. Plus you get these nice arcs -- like the healing stories in Mark this Lent, or the current arc of David and the Temple. Though I wish we covered more of the Bible in the lectionary; a 3-year cycle seems insufficient to me.
