There are a lot of Psalms kicking around this time of year. Today, Good Friday, has quite a few available to us. In the classical Prayer Books this was one of the very few days in the year that got its own set of Psalms for the Daily Office, interrupting the 30-day cycle.
Morning Prayer: 22, 40, 54
Evening Prayer: 69, 88
Looking at the modern liturgy of our 2019 BCP, it’s not quite as heavy-handed on the Office, but the options still give a similar range:
Friday Morning Prayer: 40
Good Friday Service: 22 or 40:1-16 or 69:1-22
Friday Evening Prayer: 102
Saturday Morning Prayer: 88
Holy Saturday Service: 130 or 88 or 31:1-6
Saturday Evening Prayer: 91
You’ll notice that there is a little overlap between the Psalms offered in the primary service and the Psalms offered in the Daily Office, and a lot of overlap with the traditional Prayer Book Psalms. Although the execution and placement has changed, it’s nice to see that the contents of our venerable tradition have not been lost entirely.
If you’re a worship planner for your congregation, you should observe that the primary worship service for Friday and Saturday in the Triduum offer three choices of Psalms… and our lectionary has a three-year cycle. This is not presented as a rule, but it is a logical assumption that we should cycle between those three Psalms year by year. If you want to cast an eye back to general Western tradition, the Gradual Psalm for Good Friday was from Psalm 54 and Psalm 42 for Holy Saturday, neither of which are appointed in our Prayer Book. You could, however, add them to the Daily Office Psalmody on their proper days (the former is already there in the classical Prayer Books anyway).
Furthermore, whether you’re a worship planner or not, something anyone can do is add Psalms to the recitation of the Daily Office on one’s own. Assuming you’re able to know what Psalm the main liturgy at church will use later today, you can fill in the other Psalm options to your recitation of the Office. So if Psalm 69 is featuring at the Good Friday liturgy today, then consider adding Psalm 22 to Morning Prayer; perhaps you can grab Psalm 54 from the classical Prayer Books also, to add to Evening Prayer.
Same deal with Holy Saturday; take a look at the Psalms appointed, and consider how you might use up ones “left out” this year. I mean, hey, it’s the Triduum… there’s no such thing as praying too much on days like these!
