148. And not only in Peter is there found to be one operation of the Father, the Son, and the Holy Spirit, but also in all the apostles the unity of the divine operation, and a certain authority over the dispensations of heaven. For the divine operation works by the power of a command, not in the execution of a ministry; for God, when He works, does not fashion anything by toil or art, but “He spake and they were made.” He said, “Let there be light, and there was light,” for the effecting of the work is comprised in the commandment of God.
