Thanks to Steve Thorngate ...

blogger at The Christian Century, for his kind expression of interest, and his question regarding possible implementation schedules for Year D. The short answer is that I have addressed this in Appendix C of Year D: A Quadrennial Supplement ... . The longer answer is that, while the book bears the subtitle Quadrennial, in fact the alternating option he suggests that retains the three-year "waltz" is one I have included there. The thing to bear in mind if going with a three-year alternating option is that a lot depends on when you begin. For instance, I had a post up a while back (since deleted) that presupposed (as I recall) an Advent 2010 start, since that would have followed on Year C and inserted D in lieu of Year A; thus: DBC / ADC / ABD / ABC. As it turns out, with the publication schedule for the book being Spring 2012, the first opportunity for integration based on the print source(s) would be this coming Advent, which assumes inserting D in lieu of C. Of course, there are a number of ad hoc or local options, too. But if anyone is especially worried about the cost to liturgical unity, I do think the musical/cross-rhythmic analogies (pp. 13-14) are very interesting, esp. when one considers what things might "sound like" from on high, as it were.

Thanks again, Steve, for the plug. I hope you like the book.
