ISB ~ Titus 2 v14

to redeem us:i.e., to purchase us from the bondage of sin and to purify us for a life of divine sonship. See note on Eph 1:7.

people of his own:The expression is taken from the Greek OT.

• Both Ex 19:5 and Deut 7:6 use these words to describe Israel as Yahweh’s special possession by covenant. The nation was set apart as a holy and priestly people called to draw other nations closer to God (Deut 4:6-8; Is 49:6). But since the persistence of sin and weakness prevented Israel from fulfilling this vocation under the Old Covenant, Christ came to reconstitute his covenant people in the Church (1 Pet 2:9) and to empower them to fulfill the mission once given to Israel (Mt 5:14-16). Paul’s words are also reminiscent of the New Covenant oracles of Ezekiel, especially Ezek 37:23.
