The Most Rev. Robert Christian, a Dominican friar, who has been the Auxiliary Bishop of the Archdiocese of San Francisco passed away on July 11, 2019 at age 70.
His coat of arms was assumed by him at the time of his episcopal ordination.
Umm…no. Sorry, but “beige” isn’t a heraldic color and, no, you may not just simply make up new rules and use whatever color you wish in heraldry. The science of heraldry limits the tinctures to be used and beige isn’t one of them. The Dominican cross and the usual Franciscan conformities (the arms of Christ and St. Francis crossed with each other) made for a nice combination of symbols for his Religious Community and the Archdiocese.
May he rest in peace.
EXARANDORUM 
The coat of arms for the the new bishop of Wheeling/Charleston will be an heraldic nightmare as the combination of his arms with that of his new diocese will be at best “busy”. What do you think?
We’ll see…
