These beautiful and profound meditations for the devotion of the Way of the Cross, drawn from the Summa of St. Thomas Aquinas, are found in another appendix in the excellent book addressing matters pertaining to the interior life written by Rev. Fr. Reginald Garrigou-Lagrange, O.P., The Love of God and the Cross of Jesus (trans. Sister Jeanne Marie, O. P. Vol. 2. St. Louis, MO: B. Herder Book Co., 1951).
A tangential note: please vouchsafe me a prayer or two, if you have the spare time. May God reward your charity!
