The Patristic Commentary on the Gospel for this Sunday can be found here.
The second reading is from St Paul’s epistle to the Colossians
In his suffering and his preaching, St Paul continues the reconciling work of Christ (Chrysostom. Theodore of Mopsuestia, Theodoret of Cyr). His sufferings are joined to those of Christ, and through that suffering he grows in Christ. (Ambrosiaster). What he suffers is, St Augustine adds, part and parcel of the sufferings of Christ. Paul represents all Christians in his suffering, and ultimately the Church itself, as a corporate continuation of the reconciling work of Christ. The great mystery that was hidden for ages is realised in the sacrifice and revelation of Christ. Before the Law, even before the making of the world, God had formed the economy of salvation (Chrysostom).
Chrysostom says we can see the riches of the glory of this mystery in the way in which it has brought sinful men to the dignity of angels simply through words and faith alone, without effort and labour on their part. Men who had worshipped stones and idols and who were captives of the devil, are now freed by Christ and come to a knowledge of their kinship and their salvation in and through Christ. Those who were lost and had no hope are found and live in the hope that is Christ Jesus.
