The Century's sort-by-lectionary-day tool exists primarily as a way of organizing past Living by the Word columns and Blogging toward Sunday posts in a useful way. But we also put other content there--anything from the magazine or blogs that happens to deal with a given lection in a way that could plausibly be useful to a preacher or worship planner.
So, while our lectionary columnists and bloggers mostly focus on Sundays, the lectionary pages have also collected a good bit of content related to the additional holy days of the (weekly) lectionary. Nothing's come up yet to tag to the readings assigned for the Wednesday of Holy Week; Easter Vigil, with its greatest-hits approach to Old Testament narratives, we've omitted for the opposite reason. But there are pages for today, Thursday, Friday and Saturday (the Holy Saturday readings).
