The Introit expresses our confidence in God to overcome enemies that oppose us. The Collect is a prayer that the course of the world may be ordered by the Lord and “joyfully serve Thee to quiet devotion.”
In the Epistle we ask for “deliverance” from corruption into the “liberty” enjoyed by a child of God. The Gradual continues the theme of asking for help from God lest the “Gentiles” ridicule our religion.
The Gospel teaches that Christ is the great Fisher of Men who relies upon the Apostles, priests and Bishops, for success. We are the fish drawn out of the water by the teaching of Christ from the sea of the world. In the Offertory we ask Jesus to “enlighten my eyes” and in the Secret entreat Him to “draw our rebellious wills” to Him. The Communion reflects the sentiment that the Lord is my “firmament...and ...refuge,” while the Postcommunion tells us that the Mass and Holy Sacrament of the Altar will “purify” our hearts and protect us.
3rd July is the Feast of St. Leo II Pp. C., who served the Church between 681-683 and called the Sixth Ecumenical Council which condemned the Monotheists who denied that Christ had a human will. Although not commemorated in the Mass, using the 1960 rubrics, pray to the holy Pope that our Church condemn the heretics of the day.
