Benefice operations management

Wychert Vale Benefice has a large volunteer ministry team and highly enabled lay people serving in every aspect of the churches’ ministry. Youth ministry, Fresh Expressions, ministry to elderly people, healing ministry and many other areas are lay-led. This creates a dynamic situation and also one that needs considerable nurture and management.

The Haddenham Benefice has been supported by the Parish Office in the St Mary’s Centre in Haddenham. On becoming Wychert Vale Benefice, the parish office was re-named the Benefice Office and has widened its scope to provide management for the new benefice.
