On December 17 Mark Stuart edwards, OMI will be ordained (along with Terence Curtin) as auxiliary bishop of Melbourne, Australia. Bishop Edwards is also the Titular Bishop of Garba.
His newly assumed arms (above) reflect his baptismal patron, St. Mark, as well as the Oblates of Mary Immaculate, the Religious community to which he belongs. In addition, Our Lady and Australia are alluded to on the chief.
These arms were designed by me and Mr. Richard d’Apice of the Australian Heraldry Society and emblazoned by Sandy Turnbull also of the Australian Heraldry Society.
EXARANDORUM 
Congratulations with the Edwards-arms, except the OMI letters. I saw those letters more in bishops shield of OMI-prelates.
By yhe way, did’nt mgr. Curtin adopt coats of arms?
