The Bishop Designate of Woolwich, The Venerable Alastair Cutting

Alastair grew up in a Christian family in South India, where his parents were doctors in a remote village hospital. He gave his life to Christ at the age of nine and cannot recall ever not being a Christian.

Alastair was educated at Westhill College, Birmingham University, trained for ministry at St John’s College in Nottingham and gained a Masters at Heythrop College, University of London. Although Alastair trained for ministry in an Open Evangelical theological college context, he describes his personal spirituality as informed and nurtured through Celtic and Catholic traditions, too.

He served his title post at All Saints Woodlands in Doncaster, in the Diocese of Sheffield and was ordained priest in 1988. He served as Assistant Curate at Wadsley from 1989 and in 1991 was appointed Chaplain to The Nave Arts Centre and the Town Centre in Uxbridge, in the Diocese of London.

In 1996, Alastair was appointed Vicar of Copthorne, West Sussex, in the Diocese of Chichester, and from 2010 he served as Vicar of Henfield and Rector of Shermanbury and Woodmancote.

He has been elected twice to serve on the General Synod, and twice also elected as ProProlocutor of the House of Clergy. Alastair has served in his current role as Archdeacon of Lewisham & Greenwich in the Diocese of Southwark since 2013.

As a young curate Alastair found himself dealing with the traumatic events around the Hillsborough disaster, and – much later on – with the responses around the tragic deaths of Lee Rigby and Sabina Nessa in London – which he describes as experiences that have helped form and shape him. He ran a church-based arts centre for five years in West London.

Alastair is married to Kay, a teacher of children with profound and multiple learning difficulties and special needs, and they have two grown up daughters – Hannah and Laura – as well as a black Labrador called Maia.
