 Angela's authority as a spiritual teacher may be gathered from the fact that Bollandus, among other testimonials, quotes Maximilian van der Sandt, of the Society of Jesus, as calling her the "'Mistress of Theologians', whose whole doctrine has been drawn out of the Book of Life, Jesus Christ, Our Lord".Pope Clement XI approved the veneration paid to her over the centuries in his beatification of her on 11 July 1701 and Pope Francis extended the veneration to all the Church on 9 October 2013, declaring her a saint by equipollent canonization, recognizing the validity of the long-standing veneration of her.Her feast day is celebrated by the Third Order of Saint Francis, both Secular and Regular, on 4 January (7 January in the United States).
