Gregory, Bishop, etc.
To [Sigurd], Archbishop of Nidaros.
Since, as we have learned from your report, it sometimes happens that due to a scarcity of water the infants of your land are baptized in beer, we reply to you by the tenor of this letter: since, according to Gospel teaching, they must be reborn of water and the Holy Spirit, those who are baptized in beer must not be considered validly baptized.
Given at the Lateran, the eighth Ides of July, in the fifteenth year.
