Blazon:

Arms:  Tierced Per Pale in chief Azure a ciborium surmounted on a compass star Or, in dexter Argent an ox combatant proper, in sinister Vert a tiger combatant proper.

Motto:  Robur Ex Fides

Design Rationale:

Father Thu Nguyen’s personal arms indeed carry deep symbolism, reflecting his faith and heritage. Here’s a breakdown of the elements:

In Chief (top of the shield):
Azure (blue): Represents the Holy Mother Mary. Ciborium surmounted on a compass star Or (gold/yellow): Symbolizes the body of Christ and His sacrifice for the salvation of souls.

Dexter (right side, lower left as it appears):
Argent (silver/white): Features an ox proper (as it appears in nature), representing the year of his birth.

Sinister (left side, lower right as it appears):
Vert (green): Displays a tiger proper, recognizing his Vietnamese heritage.

The Motto Robur Ex Fides Is Latin for Strength comes from Faith.
