IV.13
Gregory comments on the verse Song 2:10-12.
The winter has also, without doubt, a double meaning, because the winter is severe and cold, but it is also a time good for sowing thanks to rain. Therefore, when he speaks about winter, he evokes the time of this world because the word of God is sown in these times as a seed of justice by the prophets, apostles and priests, and the world is bedewed with incessant preaching as with heavenly rain so that it could bring forth fruit hundredfold, sixtyfold and thirtyfold [cf. Matt 13:8]. The severity and coldness of winter represent the harm of persecutions which are suffered by many saints in this world, just like the Saviour said in the Gospel: "through many tribulations we must enter into the kingdom of God" [Acts 14:21].
