309. The dignity of the Word of God requires that in the church there be a suitable place from which it may be proclaimed and toward which the attention of the faithful naturally turns during the Liturgy of the Word.[Inter Oecumenici 92]
It is appropriate that generally this place be a stationary ambo and not simply a movable lectern. The ambo must be located in keeping with the design of each church in such a way that the ordained ministers and readers may be clearly seen and heard by the faithful.
My parish’s ambo is a movable piece, though it takes two people to budge it awkwardly. The stand on which it sits is more easily moved across the floor, a concession to the possibilities of focusing the proclamation of the Word to either side of our antiphonally-seated assembly, as the situation might dictate.
From the ambo only the readings, the Responsorial Psalm, and the Easter Proclamation (Exsultet) are to be proclaimed; likewise it may be used for giving the Homily and for announcing the intentions of the Universal Prayer. The dignity of the ambo requires that only a minister of the word should stand at it.
Homily and general intercessions optional. Anybody have the intercessions announced from a place other than the ambo. I tend to lean toward that option myself.
It is appropriate that before being put into liturgical use a new ambo be blessed according to the rite described in the Roman Ritual.[Book of Blessings 900-918]
