With regard to "The Divine Liturgy of St. John Chrysostom," pp 32-34:

After the faithful receive Holy Communion, the priest lifts up the cup towards the congregation, singing the verse from Psalm 28 that is also the inspiration for the Apolytikion of the Cross: "Save, O God, Your people and bless Your inheritance." We are now the New Israel, the chosen people of God, His treasured inheritance from generation to generation.

The people respond with an exclamation of joy and a confession of faith: we have approached Christ, Who is the True Light of the world! When we receive Christ, we also receive the Holy Spirit. In fact, we experience the entire Holy Trinity, Father, Son and Holy Spirit, because the Holy Trinity is undivided: the Father is in the Son, the Son in the Father, and so also is the Spirit. Receiving Holy Communion is therefore a mystical experience: we might not see the Three Persons, we might not taste flesh and blood, and yet they are really present in a mysterious, supernatural fashion. If we are well prepared, and if we love Christ and believe in His real presence, we will have a powerful experience that might last for hours, usually the rest of the day. We are purified, uplifted, filled with joy and thanksgiving.

This is expressed collectively the the congregation in the next set of petitions. We pray specifically, once again, for a "perfect, holy, peaceful, and sinless day." We have been cleansed by the Holy Gifts and we are ready to deepen our commitment to Christ; we do so both for ourselves and for one another, as members of the Body of Christ. We do not offer Him just part of ourselves, but "our whole life." A Christian does no longer live for himself, but for the Lord and for his brethren. This is a radical departure from the worldly life that is led by most people around us; nevertheless, it is our calling as Christians to take this radical step and commit our life to our Lord and Savior. Some are called to be monastics, some to serve the Church as clergy, most of us are called to live in the world, but not to follow the ways of the world. One can follow Christ in any profession, by resisting the temptation to promote oneself and one`s family only, and learning to serve others.

Amen -- so be it!
