The month of July is dedicated to The Precious Blood of Jesus. The entire month falls within the liturgical season of Ordinary Time, which is represented by the liturgical color green. This symbol of hope is the color of the sprouting seed and arouses in the faithful the hope of reaping the eternal harvest of heaven, especially the hope of a glorious resurrection. It is used in the offices and Masses of Ordinary Time.
The Blood that coursed through the veins of Christ was a part of that Sacred Humanity made possible by the maternity of Mary, whose parents, St. Joachim and St. Anne are honored this month. (July 26). Our Lord's blood poured out on the Cross purchased our salvation, washed clean the robes of the martyrs, and gave birth to the Church as it flowed from his wounded side. The Precious Blood of Christ — now pulsing through his Mystical Body — continues its salvific work, preserving and purifying, repairing and providing nourishment for regeneration and renewal of its members.

Below is the opening prayer of the votive Mass, as well as an additional prayer that can be used as our own personal meditation or prayer during July.
O God, who by the Precious Blood of your only Begotten son have redeemed the whole world,
preserve in us the work of your mercy,
so that, ever honoring the mystery of our salvation,
we may merit to obtain its fruits.
Through our lord Jesus Christ, your son,
who lives and reigns with you in the unity of the holy spirit, one God, for ever and ever.
Admitted to your sacred table, O Lord, we have with joy drawn water from the fountains of the Savior: O may his blood, we beseech thee, become within us a fountain of water springing up to eternal life.
