His conspicuous use of a pectoral cross can be disturbing, especially when
he says things that are not becoming of anyone who is consecrated. I had
heard it denounced from the pulpit, that the laity should not be wearing
large pectoral crosses visible on the outside of their garments, and that
you can wear it inside, or under your shirt if you must.
For someone with corrosive skin, that would mean that you would have to
either have a stainless steel or precious metal cross, such as gold or
platinum or rhodium (at least plated), because silver tarnishes very quickly
with such a condition. Alternatively, such a one could just let the silver go
ahead and tarnish, to give the crucifix a dark bronzed hue like the crucifix
that Roger Cardinal Mahony put up in Our Lady of the Angels Cathedral.
Alternatively, all wood or plastic or some kind of synthetic could be used
that doesn't tarnish like silver or semi-precious or base metals do.
