My coat of arms has been created! Thanks to Guy Selvester for his fine work.
The coat of arms signifies devotion to the Blessed Virgin Mary. The crescent specifically signifies the Immaculate Conception of Our Lady. That Feast is the anniversary of my Total Consecration to Jesus through Mary (years later than I should have, mind you!). Our Lady is also the Patroness of the United States under the title of the Immaculate Conception. Finally, the crescent also appears in the coats of arms of both my family (in Ireland) and of my Alma Mater, the Catholic University of America.
The arms do resemble the familial arms. The bottom half is based upon them, with modifications (crescents were replaced with Shamrocks, recalling my heavenly Patron and the land whence my family came).
The stars are both Marian, as well as a reminder of the Diocese [and State!] of which I am a part.
The motto comes from the Book of Daniel, by way of the Holy Sacrifice of the Mass. The longer prayer in the Mass is: In spiritu humilitatis et in animo contrito suscipiamur a te, Domine, et sic fiat sacrificium nostrum in conspectu tuo hodie, ut placeat tibi, Domine Deus. -- May we be recieved by Thee, O Lord, in a spirit of humility and with contrite hearts: and may our sacrifice be such in Thy sight, that it may please Thee, Lord God.
It is incumbant upon all Christians, by virtue of their Baptism, but especially upon the ministerial Priests, to offer their entire selves to God as a living sacrifice. This is not flowery language. This is how we are to live, as giving the total gift of self, as John Paul II said.
