454. From where does the authority of the Apostle ministry derive?

The authority of the Apostle ministry derives from the calling of the Apostles by Jesus Christ and from the powers which the Lord laid into this ministry. The significance of the ministry can be seen in Jesus’ intercessory prayer: “As You sent Me into the world, I also have sent them into the world, and for their sakes I sanctify Myself, that they also may be sanctified by the truth” (John 17:18-19).
