THY testimonies are made very sure: holiness becometh thine house, O Lord, unto length of days.
“HOLINESS becometh thine house, O Lord”. “Holiness” meaning the sacrifices, the gifts, all worship owed to God. In saying that these things are becoming to the house of God, he shows that this house is not empty, nor is it a deserted by God, but that it has the Head of the Household within.
For if it were empty of God, it would hardly be becoming for it to have things becoming to God alone: this the Lord himself added to the words we have just heard, when he promised to be with his Church for ever. And St Paul calls the Church the house of the living God: for he says, “That you might know to conduct yourselves in the house of God, which is the Church of the living God”.
“Behold I am with you.” And where the Psalmist says, “unto length of days”, the Lord says, “all days, unto the ending of the age.”
St Nicholas Cabasilas (?1319-?1391), Commentary on the Divine Liturgy, §18: the Second Antiphon.
O LORD our God, save thy people, and bless thine inheritance. Preserve the fulness of thy Church. Sanctify them that love the comeliness of thy house. Do thou glorify them in their turn, with thy divine power; and do not forsake us, for we have put our hope in thee.
Liturgy of St John Chrysostom, Secret Prayer at the Second Antiphon.
