north sanctuary wall there is a decorated
niche (shallow recess, especially one
in a wall to display a statue or other ornament). Next to this is
an aumbry which is a locked cabinet or safe in the wall to hold the
consecrated (made sacred) bread and wine that has not been used during
the normal communion. This can then be taken to the ill or housebound
who have asked for communion to be given to them at home.
A wax sanctuary lamp stands in the niche next to the aumbry as a sign
that this sacrament is stored here. The lamp is always burning to
remind us that Christ is always present.
