It is essential to summon the priests to confirm with prayers and blessings the couple in their life together, so that the groom’s love might intensify, the bride’s chastity of mind be strengthened, everything work to ensure that the virtues settle into their home, the machinations of the devil be scattered, and that the couple, united through God’s help, might spend their life in joy.
The husband must bear in mind that his deeds and words should engender piety in his home. The wife must look after the house. However, in addition to that occupation, she must also attend to another, more pressing concern - that the whole family strive [to attain] the Heavenly Kingdom.
Holy Hierarch John Chrysostom
Comprising one flesh, [the couple] also has a single soul, and their mutual love awakens in them a zeal for piety. For the state of wedlock does not estrange us from God, but rather ties us more closely to Him, for it brings forth a greater impetus to turn to Him. Even under a light breeze, a small boat moves forward... a light breeze will not move a great ship... Thus, those not burdened with secular concerns have less need of help from Almighty God, but one who has responsibilities, who looks after his beloved spouse, his estate and his children, traverses a broader sea of life, and has greater need of God’s help. In return [for that help], he himself comes to love God even more.
Holy Hierarch Gregory the Theologian
