Mobsby was born in the heady days of the late 1960s, with a family inheritance of atheism and socialism on his mother's side and science, the arts and banking on his father's side. At an early age he took to music, which became a key motif to his life, particularly with the classical guitar and violin. He also had a love of nature and has described in his writing how this opened up the experience of spirituality in nature. He trained for a BHSc in occupational therapy at York St John University which was formally part of the University of Leeds at the time. It was while studying in York that Mobsby became a committed Christian, largely through an alternative worship project then called Warehouse and now called Visions.
Vocation and ministry
Mobsby completed an MA in Pastoral Theology validated by Anglia Ruskin University and taught through the Cambridge University's Cambridge Theological Federation part-time whilst still working split between Occupational Therapy and working as a lay pioneer. At the end of training, he was released from the Southwark diocese to be involved in forming a new missional and fresh expression of church at the Church of England church called St Matthew's Westminster in the Diocese of London. He was ordained by the Bishop of London to serve a training title with St Matthew's, Westminster and the Moot Community. In the second year of his curacy and work with Moot, Mobsby met with the new Archbishop's Missioner the then Revd Steven Croft now Bp of Oxford, where he was formally invited to become an Associate Missioner of the new Fresh Expressions initiative. At the same time Mobsby completed his MA research dissertation, Emerging and Fresh Expressions of Church, how are they authentically Church and Anglican?. Mobsby has founded several new monastic communities that include the Wellspring Community Peckham and the Moot Community, drawing heavily on a contemplative and sacramental basis to the Christian faith which seeks to promote a focus on following Jesus and in particular live out the marks of mission in how the community lives. Both the Wellspring Community and Moot Community have become leading new monastic communities in the UK. In 2011 Mobsby was co-opted onto the Church of England's Advisory Council for the relations between Diocesan Bishops and Religious Communities to help this Anglican body discern a way forward to recognise New Monastic Communities as Acknowledged Religious Communities. After a lengthy period of discernment Mobsby was the first elected Guardian of the newly constituted Society of the Holy Trinity, a new Society for the promotion of Anglican & Epsicopal missional new monastic communities in the UK and beyond.
Theology
Mobsby has written about the Holy Trinity as the ultimate source of his theology and missiology. Phyllis Tickle stated: Mobsby makes connections between God as an event of grace, and a happening to inform his understanding of God and God's salvific purposes for all people, as God seeks to restore all things back into right relationship with the divine.
