Parishes and deaneries
The 75 parishes in the diocese are divided into nine deaneries. Where after the title of a church two dates are given, the first is the date of the foundation of the parish and the second is the date of the opening of the current church building. Due to a shortage of priests, a number of parishes have begun to share parish priests, forming pairs of linked parishes.
There are 11 priests and 1 deacon who serve as school chaplains to the high schools in the diocese.
There is also a chaplain to the main hospitals in the diocese, Monklands (Rev James Travers), Wishaw (Rev Ricklan Mallya) and Hairmyres (Rt Rev Mgr Thomas Millar).
Our Lady of Good Aid Cathedral was first built in 1900 and became the cathedral of the new diocese of Motherwell in 1948. The current Cathedral Administrator is Fr Gerard Chromy. The parish of the cathedral was linked with the parish of St Luke's Motherwell in 2011.
