677. How is the ordination performed?

Ordinations are performed exclusively by Apostles. After an address by the Apostle, those to be ordained are asked whether they are prepared to accept the ministry. They are also asked whether it is their intent to serve God faithfully, stand up for the gospel of Jesus Christ, and exercise the ministry in accordance with the New Apostolic Creed. They are further asked if they are prepared to exercise the ministry in the mind of Jesus Christ, in love for the believers, and in obedience of faith.
They vow this before God, who calls them into His service, and before the congregation, by saying “yes”. While kneeling, they then receive the ministry through the laying on of hands and prayer of the Apostle.
