Rev. Dr. David Ault will be coming to Cambridge along with Rev. Dr. Frankie Timmers and Rev. Trish Hall on April 26 for the Ordination of the Rev. Edwin F. Tanzi (Rev. Ed) and Rev. George L. Stewart (Rev G).

Before becoming eligible for ordination, a minister has to complete at least three years of continuous, active service as a licensed minister and pass a review by a panel of other ordained ministers. Unlike other denominations, the Centers for Spiritual Living does not ordain its ministers upon graduation, instead it allows ministers to work in the field before they fully commit to ministry.

On Sunday, April 28, Ault will be the guest speaker at the Sunday Celebration Service located at 50 Dudley Street, Cambridge. He will also lead The Worry Workshop: Creating a New Relationship with an Old Problem from 1 to 3 p.m. Space is limited; call for a reservation.

Rev. Ed and Rev. G are the co-founding ministers of the CSL Greater Boston. They are master teachers of mental science approaching life as a path in personal evolution and growth, revealing spiritual truths behind every experience. Most importantly, they assist in self-empowerment. They have transformed many lives in weekly classes, outreach programs, workshops and Sunday services.

Cost: $54.95 adult; $24.95 child. Location: 282 Bennington St., East Boston. For more information, call 617-947-2743 or visit CLSBoston.org.
