English: The shield is divided into four quarters with wavy horizontal lines from top to bottom. In the first and fourth quarters the lines alternate blue and silver (white) while in the other two quarters they alternate red and gold (yellow).

The blue and white lines represent the Blessed Virgin Mary. In addition, they suggest water which also alludes to Jesus washing the feet of His disciples. In addition, they can be seen as referring to the waters of Baptism. The red and gold (yellow) lines represent the Holy Spirit and fire. In addition, the colors can be seen as referring to the Blood (as well as water) that poured from the side of the Lord at His crucifixion. They are also seen as referring to bread (gold/yellow) and wine (red) as a reference to the Eucharist. In this way these lines also refer back to the foot washing because Jesus was showing His disciples the kind of self-sacrificing service they were called to which was about to be played out in His sacrifice on the cross and would be experienced for them in the future whenever they came together to share the Eucharist.

At the center of the shield is a silver (white) roundel called a plate. On this plate is a simple symbolic representation of the Mandatum (washing of the feet). The outer edge of this roundel, or plate is a line composed of small humps. Such a line is called “invected” in heraldry. It is borrowed from the coat of arms of the Diocese of Yakima, WA where Bishop Pulido served as a priest before being named a bishop.

The motto below the shield is, “Building Communio” which is what the bishop sees as the purpose and goal of his episcopal ministry.
