Numbered sections 14 through 16 introduce the Liturgy of Dedication which takes place after the homily and before the Liturgy of the Eucharist. The first part of this would be the placement of the relics:
14. If it is to take place, the relics of a martyr are deposited after the singing of the Litany of the Saints, to signify that the sacrifice of the members has its source in the sacrifice of the Head. When relics of a martyr are not available, relics of another saint may be deposited in the altar.
15. The celebration of the eucharist is the most important and the one necessary rite for the dedication of a church.
Nevertheless, in accordance with the tradition of the Church in both East and West, a special prayer of dedication is also said. This prayer is a sign of the intention to dedicate the church to the Lord for all times and a petition for his blessing.
And we would expect the centrality of the Eucharistic celebration here. The local community really cannot do without a cleric, preferably a bishop.
