"Firmeza en la verdad." Francisco de St. Thoma, in his Medulla Mystica, p. 204, quoting this passage, has, "firmeza en la voluntad." Philip a SS. Trinitate, Theolog. Mystic. p. 354, and his Abbreviator, Anton. a Sp. Sancto, Direct. Mystic. tr. iv. disp. i. § 11, n. 94, seem also to have preferred "voluntad" to "verdad;" for the words they use are, "nec intellectui lux nec voluntati firmitas;" and, "defectus lucis in intellectu, et firmitatis in voluntate."
