The Prayer pleads for God to visit His Church "continually" with Divine Life. We act as the children of this Church, reborn and restored to the "life of the Spirit" by instructing others in the work in which we have been "instructed" and do ing "good to all men" (Epistle); by morning and evening prayers to Him Who is "King above all the earth" (Gradual) throughout our entire day.
The Sacramental Life is our defence against diabolical attack (Secret and Communion). A life long war goes on between the death dealing flesh and the everlasting spirit; hence the Postcommunion counsels us that, not the "impulses of nature," but rather the "graces of the Eucharist" should dominate our life.
Today is Feast of St. Laurence Iustinian E. C., XV Century Patriarch of Venice, known for his life of constant prayer and austerity. Although not commemorated in the Mass using the newer rubrics, we might regard him as a model for our own life.
