The Psalms have been a central ingredient used by the Holy Spirit in my Christian formation.
I’ve done several posts sharing some of the many quotations and ruminations I’ve collected over the years. [I’ll send the 6 page pdf of a teaching handout to anyone who requests it. You can email your request directly.]
My definition of Psalmody? It’s the continuous, systematic reading and praying of the Psalms (whether saying or singing; whether alone or liturgically).
