Auxiliary Bishop of Brownsville, Texas
According to the Roman Catholic Church’s heraldic tradition, the Coat of Arms of a Bishop is normally composed of:
• a shield with its charges (symbols) coming from family, geographic, religious and historical meanings and/or referred to the name of the Bishop;
• a golden processional cross, with one traversal bar, to represent the rank of the Bishop, “impaled” (vertically) behind the shield;
• a green hat (galero) with 12 (six on each side) attached tassels, ordained 1; 2; 3; from the top;
• a scroll with the motto, written generally in black, below everything.
“CARITAS DEI DIFFUSA EST IN CORDIBUS NOSTRIS”
(Romans 5:5)
The shield is divided into three parts in an inverted “Y” shape known in heraldry as tierced per pall reversed.
The upper left portion (dexter chief) with a red background contains a triple-towered castle, the central tower being higher and winged all in gold, opened and with windows in black, placed on a silver field with blue waves.
The upper right portion (sinister chief) with a gold background contains a field of red roses.
The middle portion (middle base) with a blue background contains three eight pointed gold stars.
For his motto Bishop Avilés has chosen these words, “Caritas Dei diffusa est in cordibus nostris,” (translated as “The Love of God has been poured out into our hearts”) recalling the epistle from St. Paul to the Romans 5:5 and used in the Holy Mass at the introit for the feast of St. Philip Neri in remembrance of his mystical experience while praying in the catacombs of St. Sebastian in Rome.
The achievement is completed with the external ornaments which are a gold processional cross, that is placed in back of and which extends above and below the shield, and the pontifical hat, called a “galero,” with its six tassels, in three rows, on either side of the shield, all in green. These are the heraldic insignia of a prelate of the rank of bishop by instruction of The Holy See.
The triple-towered castle is taken from Bishop Avilés’ family name and represents the importance of the essential virtues and unity inherent to family life.
The field of red roses is to honor the Blessed Virgin Mary in her title of Our Lady of Guadalupe recalling the Mexican heritage of Bishop Avilés and the miracle of the roses that our Lady used to impress her image on the tilma.
The three eight pointed gold stars on a blue field is taken from the Neri family crest and used for the Congregation of the Oratory of St. Philip Neri which Bishop Avilés has been a member of since the beginning of his vocation.
The Coat of Arms was prepared by A. Bianco, L. Costa, and F. Cantone.

El escudo está dividido en tres partes en forma de “Y” invertida, conocida en heráldica como terciado en perla invertida.“CARITAS DEI DIFFUSA EST IN CORDIBUS NOSTRIS”
