From Ulrich Lehner at First Things, six points of congruence with Pope Francis, including a note on gentleness:
(He) was, like his most famous follower, St. Alphonsus of Liguori, a teacher of gentleness. In his renowned “Introduction to the Devout Life” (1609), DeSales shows himself to be a sensitive pastor who takes human frailty seriously, warning against shepherding with harshness and rigorism.
Joseph McAuley in that first link above, reminding us of the bishop’s important message on peace:
Do not lose your inner peace for anything whatsoever, not even if your whole world seems upset. If you find that you have wandered away from the shelter of God, lead your heart back to Him quietly and simply.
I was surprised I never recommended you read the Trappist William Meninger’s “reboot” of The Introduction to the Devout Life, which he titled The Committed Life. This is an outstanding spiritual book.
