Titus 2:14

Who gave himself for us - See the notes at Ephesians 5:2.

That he might redeem us from all iniquity - The word here rendered “redeem” - λυτρόω lutroō, occurs only here and in Luk 24:21; 1 Peter 1:18. The noun, however - λύτρον lutron, occurs in Matthew 20:28; and Mark 10:45; where it is rendered “ransom;” see it explained in the notes at Matthew 20:28. It is here said that the object of his giving himself was to save his people from all iniquity; see this explained in the notes at Matthew 1:21.

And purify unto himself -

(1) Purify them, or make them holy. This is the first and leading object; see the notes at Hebrews 9:14

(2) “Unto himself;” that is, they are no longer to be regarded as their own, but as redeemed for his own service, and for the promotion of his glory; - Notes, 1 Corinthians 6:19.

A peculiar people - 1 Peter 2:9. The word here used (περιούσιος periousios) occurs nowhere else in the New Testament. It means, properly, having abundance; and then one’s own, what is special, or peculiar (Robinson, Lexicon), and here means that they were to be regarded as belonging to the Lord Jesus. It does not mean, as the word would seem to imply - and as is undoubtedly true - that they are to be a unique people in the sense that they are to be unlike others, or to have views and principles unique to themselves; but that they belong to the Saviour in contradistinction from belonging to themselves - “peculiar” or his own in the sense that a man’s property is his own, and does not belong to others. This passage, therefore, should not be used to prove that Christians should be unlike others in their manner of living, but that they belong to Christ as his redeemed people. From that it may indeed be inferred that they should be unlike others, but that is not the direct teaching of the passage.

Zealous of good works - As the result of their redemption; that is, this is one object of their having been redeemed; Notes, Ephesians 2:10.
