Isaías 11
Athanasius of Alexandria · Comentário Patrístico (catena)
Isaías 11:5
At all times let us stand firm, but especially now, although many afflictions overtake us and many heretics are furious against us. Let us then, my beloved brothers, celebrate with thanksgiving the holy feast that now draws near to us, "girding up the loins of our minds," like our Savior Jesus Christ, of whom it is written, "Righteousness shall be the girdle of his loins, and faithfulness the girdle of his reins." — FESTAL LETTER 3
Isaías 11:9
But now, to all the earth has gone forth their voice, and all the earth has been filled with the knowledge of God, and the disciples have made disciples of all the nations, and now is fulfilled what is written: "They shall be all taught of God." And then what was revealed was but a type; but now the truth has been manifested. — Discourses Against the Arians 1.13.8
