When the church had been cleared of all except the faithful, the second part of our mass, or the mass of the faithful, began with the Nicene symbol or creed. Then followed the offertory, or part of a psalm sung anciently while the people made their offerings to the church, particularly of bread and wine13. The priest offers to God the bread, and wine mixed according to apostolic tradition14 with a little water, which our Saviour is believed to have mixed with the wine at the last supper; he implores God's blessing on these offerings, and washes his hands in token of the purity of soul15 with which the sacred mysteries should be approached, and at high mass for the sake of outward cleanliness also, on account of the incense which he has used. Having commemorated the passion, resurrection, and ascension of Christ, as he does also after the consecration, he calls on those present to join him in prayer, he says another prayer or prayers called the secret, because said in secret, and then recites the preface to the canon, a prayer in which he unites with the celestial spirits in praise and thanksgiving as Christ himself gave thanks at the last supper: it concludes with the Tersanctus or Trisagion "Holy, Holy, Holy etc." which, as Palmer observes, has been probably used in the Christian liturgy of the east and west since the ages of the apostles.
