beward of Arius!

When it is taught, and the passage Matt. 28:18: All power is given unto Me, etc., is thus interpreted and blasphemously perverted, namely, that all power in heaven and on earth was restored, that is, delivered again to Christ according to the divine nature, at the resurrection and His ascension to heaven, as though He had also according to His divinity laid this aside and abandoned it in His state of humiliation. By this doctrine not only the words of the testament of Christ are perverted, but also the way is prepared for the accursed Arian heresy, so that finally the eternal deity of Christ is denied, and thus Christ, and with Him our salvation, are entirely lost if this false doctrine were not firmly contradicted from the immovable foundation of the divine Word and our simple Christian [catholic] faith.
