St Mark’s is a typically “Anglican” parish: unlike its neighbours it is neither Anglo-Catholic nor Evangelical in tradition, and attracts worshippers who are comfortable with a restrained, recognizably Anglican liturgy.

St Mark’s uses Common Worship on Sundays and the English Hymnal, and the Sunday liturgy is modern catholic – vestments, lights, nave altar (although communion is received at the high altar). Incense is not used and the sacrament is not currently reserved.

There is a pricket stand in the St Mark’s/Lady Chapel where candles can be lit. The St Mark’s/Lady Chapel is currently used for the Wednesday evening BCP communion.

We greatly value the children of our community and have strong links with Clerkenwell Parochial School, 4th Clerkenwell Guide group, and 1st Islington Scout group. Children are encouraged to become servers, read lessons, assist as sidesmen, etc. and take a pride in being part of our community.

The Hall has been developed into offices for The World Community for Christian Meditation and their publishing wing Medio Media. The side chapel off the narthex is used for meditation twice a day during the week. Trinity Church Islington meet in St Mark's for worship and bible study.
