Augustine of Hippo

The baptized have, then, something to do in themselves, that is, in the temple of God that is first built and dedicated at the end. It is built after the captivity, as the title of the psalm indicates: when the enemy who had taken them captive has been expelled. There is something noteworthy in the order of the psalms. The psalm of the dedication of the house precedes in order of numbering the psalm of the building of the house. The psalm of the dedication comes first, because the psalmist is singing of the house of which its Architect says, "Destroy this temple, and in three days I will raise it up." The later psalm, when the house was being built after the captivity, foretold the church. Moreover, its opening words are "Sing to the Lord a new song, sing to the Lord all the earth." Let no one foolishly think that a baptized person is already perfect, therefore, merely because it has been said, "For holy is the temple of God, and this temple you are," and, "Do you not know that your members are the temple of the Holy Spirit, who is in you, whom you have from God?"
