Siecienski characterizes Jerome's views on the procession of the Holy Spirit as "defying categorization". His name is often included in Latin florilegia as a supporter of the filioque and Photius even felt called to defend Jerome's reputation against those who invoked him in support of the doctrine. However, because Jerome's writing contains scant references to the doctrine and even those are "far from ambiguous affirmations of a double procession", Orthodox theologians such as John Meyendorff have argued that he "could hardly be regarded a proponent of the filioque".
