Who brought Christ back from the dead?

All three Persons of the Trinity cooperated in bringing Jesus back from the dead. You can see this in a variety of passages. Acts 2:24, 3:15, and 4:10 stress the role of God the Father in the Resurrection, John 10:18 stresses Christ’s role, and Romans 1:3 stresses the role of the Holy Spirit.

This reflects the teaching that all three Persons of the Trinity cooperate in any divine action outside the Godhead, as shown in the Creation of the world (Gn 1:1-2:4, Ps 33:6, Jn 1:3, Acts 17:24) and the birth of Christ (Lk 1:35, Jn 5:36, 6:38).
