The Archbishop of York, Stephen Cottrell, will join members of Mothers' Union from across the Diocese of York this Saturday (8 August) for a special celebration marking the organisation's 150th anniversary, held on the eve of Mary Sumner Day.
Beginning with a community picnic in Dean's Park at 3pm and followed by Evensong at York Minster at 5.30pm, where the Archbishop will preach, the event celebrates 150 years of Mothers' Union's Christian mission to support families and strengthen communities around the world.
The date is especially significant as it falls on the eve of Mary Sumner Day (9 August), when the Church commemorates Mothers' Union founder Mary Sumner. Founded in 1876 in Hampshire, Mothers' Union has grown into a worldwide Christian movement with members in more than 80 countries, united in faith, prayer and action to support family life and build stronger communities.
Archbishop Stephen said: ‘For 150 years, the Mothers' Union has remained faithful to Christ while continually responding to the changing needs of the world. As we celebrate this remarkable anniversary, we give thanks for all that God has done through countless small acts of faith and service, and we look ahead with confidence, asking where God is leading us next.’
The celebration is open to everyone. Attendees are invited to bring their own picnic and join members, supporters and the wider community in giving thanks for the organisation's rich heritage and looking ahead to its continuing mission.
