The Gathering

Et congregatae sunt, ad eum turbae multae, ita ut naviculam ascendens sederet: et omnis turba stabat in littore Turba multa ad Dominum docentem congregata, significat frequentiam populorum, praedicantibus apostolis, ad Christum confluentium. Quod ascendens navim, sedebat in mari, significat quod Christus per fidem ascensurus erat in mentes gentilium, et Ecclesiam collecturus in mari, id est in medio nationum contradicentium, in qua Ecclesia dicitur sedere, hoc est regnare et dominari. Turba vero quae stabat in littore, quae neque in mari, neque in navi erat, gerit figuram recipientium verbum Dei, et jam fide a mari, id est a reprobis separatorum, sed necdum per gratiam baptismatis in Ecclesia intromissorum. Anselmus Laudunensis, Enarrationes In Matthaeum, Caput XIII Source: Migne PL 162.1369b

And great crowds gathered to Him, so that He went up into a boat and sat, and all the multitude stood on the shore. 1 Many crowds were gathered for the teaching of the Lord, which signifies the many peoples sent flowing to Christ by the preaching of the Apostles. That He got up into the boat and was sat in the sea signifies that by faith Christ was to rise up in the minds of the Gentiles and the Church was to be gathered in the midst of the sea, that is, in the midst of dissentient peoples, in which the Church is said to sit, which is to rule and reign. But the crowd that stood on the shore, who were neither in the sea nor in the boat, these bear the figure of those who receive the word of God and by faith have been drawn out of the waters, that is, from among the wicked, but they have not yet entered into the Church through the grace of baptism. Anselm of Laon, Commentary On The Gospel of Saint Matthew, Chapter 13 1 Mt 13.2
