St-Basil-the-GreatThou art more beautiful than the sons of men: grace has been shed forth on thy lips: therefore God has blessed thee for ever. Gird thy sword upon thy thigh, O Mighty One, in thy comeliness, and in thy beauty (Psalm 44[45]:2-3).

‘Grace is poured abroad in thy lips; therefore hath God blessed thee forever’ (Ps. 44:2). In the Gospel it has been written: ‘They marvelled at the words of grace that came from his Mouth’ (Luke 4:22).

The psalm, wishing to bring forward vividly the great amount of grace in the words spoken by our Lord, says: ‘Grace is poured abroad in thy lips’ because of the abundance of grace in the words.

‘God hath blessed thee forever’ it says. It is evident that these words refer to His human nature, as it advances ‘in wisdom and age and grace’ (Ibid. 2:52).

According to this we clearly perceive that grace has been given to Him as the prize for His brave deeds. Similar to this is the saying: ‘Thou hast loved justice and hated iniquity: therefore God, thy God, hath anointed thee with the oil of gladness above thy fellows’ (Ps. 44:7).

The saying of Paul to the Philippians is also much like to this: ‘He humbled himself, becoming obedient to death, even to death on a cross. Therefore God also has exalted him’ (Phil. 2:8). So that it is clear that these words were spoken concerning the Savior as a man.

Or, there is this explanation. Since the Church is the body of the Lord, and He Himself is the head of the Church, just as we have explained that those ministering to the heavenly Word are the lips of Christ (even as Paul, or anyone else much like to him in virtue, had Christ speaking in himself [cf. 2 Cor. 13:3]’), so also we, as many of us as are believers, are the other members of the body of Christ.

Now, if anyone refers to the Lord the praise given to the Church, he will not sin. Therefore, the saying: ‘God hath blessed thee’; that is to say, He has filled thy members and thy body with blessings from Himself for eternity, that is to say, for time without end.

‘Gird thy sword upon thy thigh, O thou most mighty. With thy ripeness and thy beauty’ (Ps. 44:3).

We believe that this refers figuratively to the living Word of God, so that He is joined with the flesh, who is ‘efficient and keener than any two-edged sword, and extending even to the division of soul and spirit, of joints also and of marrow, and a discerner of the thoughts and intentions of the heart’ (Heb. 4:12).

[…] He is a sword that cuts through the sensual part of the soul and mortifies the motions of concupiscence.
