The coat of arms above is a combination of the diocesan coat of arms, on the left side of the shield, with the bishop's personal coat of arms on the right. Together they symbolize the spiritual union of the bishop with his spouse, the local Church.

In the bishop's personal coat of arms, the Greek letters, Chi and Rho, at the center of the design, symbolize Christ. 

As disciples of the Lord, we seek “to know Christ and the power flowing from his resurrection (symbolized by the palm branches); likewise to know how to share in his sufferings by being formed into the pattern of his death (symbolized by the cross).” (cf. Phil 3:10)

We are to continue God’s work of reconciling everyone to Christ in the mystery of his death and resurrection. This is suggested by the circle tied into the cross and palm branches.

Bishop Brom selected the motto, "Ego Sum Christi" or "I Belong to Christ" (I Cor 1:12) to express his commitment to Christ and dedication to the Church. Consecrated in truth, Bishop Brom professes to belong to Christ and not to the world (cf. John 17.) and for this privilege, he wants above all else to be an ambassador for Christ and a minister of reconciliation (cf. II Cor 5:14-21) and to love the Church as Christ loved the Church, giving himself up for it (cf. Eph 5:25).
