Isaiah 63:16

Abraham, &c. That is, Abraham will not now acknowledge us for his children, by reason of our degeneracy; but thou, O Lord, art our true father and our redeemer, and no other can be called our parent in comparison with thee. (Challoner) --- Abraham is not able to save us. (Calmet) --- The patriarchs may justly disregard us, as degenerate children; yet we hope in God's mercies. Thus St. Jerome, &c., explain the passage, which does not favour the errors of Vigilantius and of Luther, who maintain that the saints departed do not know what passes in this world. St. Augustine (Cura xv.) shews the contrary, from the example of Lazarus, Luke xvi. They know each other, though they had not lived together, (St. Gregory, Dial. iv. 33.) and beheld in the light of God what regards their clients. (St. Augustine, City of God xxii. 29.) We cannot decide how the martyrs do help those whom it is certain they assist. (St. Augustine, cura xvi., and contra Faust. xx. 21.; St. Jerome, contra Vigil.; St. Gregory, 3 ep. 30., and 7 ep. 126., &c.) (Worthington)
