The church of Our Lady of Mount Carmel and St Simon Stock is a Roman Catholic church at 41 Kensington Church Street, Kensington, London W8, served by Discalced Carmelites.
It is a Grade II listed building, built in 1954 to 1959, and designed by Sir Giles Gilbert Scott.
The offertory (from Medieval Latin offertorium and Late Latin offerre) is the part of a Eucharistic service when the bread and wine for use in the service are ceremonially placed on the altar.
A collection of alms (offerings) from the congregation, which may take place also at non-Eucharistic services, often coincides with this ceremony.
