Lister Tonge, AKC (born 23 December 1951) is a Roman Catholic Transitional Deacon and former British Anglican vicar.
He, alongside Archdeacons Jonathan Williams and Ambrose Mason, raised grievances - which they termed "concerns about the well-being" - against the Bishop of Monmouth, Richard Pain.
Despite an internal investigation which determined that there was insufficient evidence to proceed with a formal disciplinary tribunal and finding "there was no case to answer", the three men remained unsatisfied.
Tonge, Williams and Mason then wrote a letter to the Archbishop, John Davies, and all Welsh bishops expressing how unhappy they were with the outcome.
A process of mediation was then put into place, they withdrew from this in December 2018 when a press release from the Church in Wales seemed to confirm the breakdown-in-relationships rumours.
