Gregory to Isacius, Bishop of Jerusalem.

What does the story of the flood teach us? The human race outside the ark perished; those inside were preserved for life. We see the same truth plainly now: all the unfaithful perish under the wave of their sin, while the unity of the holy Church, like the compactness of the ark, preserves the faithful in faith and charity. That ark was built of incorruptible timber -- strong souls who persevere in good. When someone converts from a secular life, it is as though timber is being cut from the mountains. When that person is given charge over others according to the order of the holy Church, it is as though the ark is being built from that timber -- for the preservation of human life. And when the flood was over, the ark rested on a mountain. So too, when the corruption of this life has passed and the waves of evil have subsided, the holy Church will rest in the heavenly country, as upon a high mountain.

I rejoice, after reading your Fraternity's letter, to find that you lend your aid to the building of this ark through the integrity of right faith. I give great thanks to Almighty God, who, though the shepherds of his flock change, keeps the faith he delivered to the holy Fathers unchangeable.

The excellent preacher Paul says, "No one can lay any foundation other than the one already laid, which is Jesus Christ" (1 Corinthians 3:11). Whoever holds firmly to faith in Christ, with love of God and neighbor, has laid Christ himself as his foundation. And where Christ is the foundation, the building of good works will follow.

The Lord also says, "The one who does not enter the sheepfold by the gate, but climbs in some other way, is a thief and a robber; the one who enters by the gate is the shepherd of the sheep" (John 10:1). To enter by the gate is to enter through Christ -- to think and preach what is true about the Creator and Redeemer, and to live what one preaches.

I urge your Fraternity: hold fast to this foundation. Guard the faith. Feed the flock.
