Philippians 3:10

Epistle of Ignatius to the Ephesians

For He is my hope; He is my boast; He is my never-failing riches, on whose account I bear about with me these bonds from Syria to Rome, these spiritual jewels, in which may I be perfected through your prayers, and become a partaker of the sufferings of Christ, and have fellowship with Him in His death, His resurrection from the dead, and His everlasting life.[86]

Fragments from the Lost Writings of Irenaeus

For it renders us like to Christ, if we experience "the power of his resurrection and the fellowship of His sufferings."[68]

Origen Against Celsus Book II

and this, "Being made conformable to His death,"[177]
