The exposition of the Liturgy of St. James, which is basically the Celebration of the Holy Eucahrist, is most significant for the understanding of the mystery of God in offering His only Son a vicarious sacrifice for the redemption of man. To make it understandable, Rev. Saka explains not only the meaning of terms connected with the liturgy but of all the components of the vessels, the vesting, the censoring, the candles and the propitiatory prayers associated with them. This exposition should benefit both church and liturgical scholars and lay people interested in the profound spiritual meaning of their faith.
