On the Deacon
Through the bishop, Christ is represented to us; through the deacon, the apostolic order. The deacon who reads is Peter, who responds on behalf of everyone. The bishop blesses the deacon before he reads because Christ, having called his disciples together, filled them with blessing and gave them power over all demons, and sent them to preach the kingdom of God (Luke ix). The deacon takes the Gospel from the altar and proceeds to read, because the law went out from Sion, and the word of the Lord from Jerusalem (Isaias ii). For in this place, the altar signifies Jerusalem, in which the apostles received the word of preaching from the Lord, and going out preached throughout the whole world. The deacon carries the book in his left arm, because the left signifies the present life. And only in this life must the Gospel be preached, for in the future life no one will lack doctrine, for all from the least to the greatest will know the Lord. He ascends the ambo from the southern side, because Christ arrived in Jerusalem from Bethlehem, which is to the south, whence it is said: the Lord will come from the south (Habacuc iii).
Per episcopum, repraesentatur nobis Christus; per diaconum, ordo apostolicus. Diaconus qui legit, est Petrus qui pro omnibus respondet. Episcopus lecturum diaconum benedicit; quia Christus convocatis apostolis, benedictione eos replevit, dum eis potestatem super omnia daemonia dedit, et eos regnum Dei praedicare misit. Diaconus Evangelium ab altari accipit, legere pergit, quia de Sion lex, et verbum Domini de Hierusalem exivit . In hoc quippe loco, altare Hierusalem designat, in qua apostoli verbum praedicationis a Domino acceperunt, et exeuntes per totam terram praedicaverunt. Diaconus in sinistro brachio librum portat, quia sinistra praesentem vitam significat. Et in hac vita tantum praedicari Evangelium debet; quia in futura vita nullus doctrina eget, nam omnes a minimo usque ad maximum Dominum cognoscent. Ab australi parte in ambonem ascendit, quia Christus a Bethlehem, quae est ad austrum, Hierusalem venit, unde dicitur: Deus ab austro veniet.
