Ministers
From the late 1970s to 2021, St Mary’s was also the home of the Methodist Church in Rickmansworth. Initially, the two churches just shared the building. Over time, the two became more integrated, eventually sharing all worship and activities.
This formal Local Ecumenical Partnership came to an end in 2021.
This is a list of the Methodist ministers who served at St Mary’s during this period.
