The Rev. Christopher Potter, Vicar

Fr. Christopher was appointed vicar of St. John’s Church and School in May 2017.¬† St. John’s Church has nearly¬†300 members; St. John’s School has about 450 students, ranging from infants to kids in eighth grade.¬†

Fr. Christopher’s path to St. John’s is fascinating! Born into the¬†Roman Catholic tradition, Christopher felt God’s call to ministry¬†around the age of 13. He received¬†a B.A. in Philosophy, with a music minor, from¬†The University of¬†San Diego, and an M.Div in Ministry, from St. John’s University, Collegeville Minnesota. He was ordained a Catholic priest in 1982, and served in several pastoral assignments¬†in Riverside and San Bernardino Counties. He¬†took leave from parochial ministry,¬†married, raised¬†a family, and¬†built a few businesses along the way.

Fr. Christopher Potter

Though living and working in the secular world, Christopher always sought¬†to¬†bring healing where people were broken and isolated and to offer hope to people who were in desperate straits. “I realized that my heart¬†and activities¬†had never left priestly ministry¬†and¬†after fifteen years as an Episcopal layman,¬†I¬†asked Bishop Bruno to accept me as an Episcopal priest in the Diocese of Los Angeles. Now I’m a single father of an adult daughter and doing what I love most in life!”

At St. John’s, Fr. Christopher sees his priestly role as fostering and nurturing hope. “My passion and education merge at the intersections of liturgy, education,¬†personal response¬†to the Gospel of Jesus, and encouraging people to join in the work of fulfilling God‚Äôs reign on earth. A priest is called to be the mid-wife of hope.¬†

“With humility and prayer,¬†priests are called to¬†enter with God into people‚Äôs lives when loss, injury or¬†death have robbed them of vision. Together with them and¬†with¬†God‚Äôs grace, priests give birth to hope and rebuild lives. We find amid tragedy the unending love God has for the world as seen and taught by Jesus.”

Fr. Christopher previously served as Assisting Priest at St. Stephen’s and St. Joseph in Buena Park, and most recently as Priest-in-Charge at Church of the Blessed Sacrament in Placentia from 2013 to April 2017.¬†

In the Episcopal Church, Christopher served on two diocesan committees: the Bishop’s Liturgy Committee, and the Diocesan Committee on Disabilities. He also holds licenses/certifications in California as a Group Home Administrator, Adult Residential Facility Administrator, and is a Certified Instructor in Non-Violent Crisis Intervention and Prevention.

In his free time Fr. Christopher enjoys spending time with his daughter, cooking, and riding his bicycle 15 miles a day.

The Rev. Karen S. Maurer, Retired Priest in Residence

NOTE: Rev. Karen Maurer retired in September 2022 but remains a presence on the St. John’s campus.

Rev. Karen was baptized a Presbyterian, confirmed in the Lutheran Church, and finally arrived at the Episcopal Church in 1982, and was received into TEC shortly after. Before going to Seminary, Karen taught Sunday School, worked in various leadership positions which included Vestry (twice), worship leadership, Cursillo ministry, Bible Studies in two Episcopal Churches ‚ÄĒ St. Clement‚Äôs in San Clemente and Emmanuel, Fullerton. In addition, after their children were mostly grown, Karen worked for Capistrano Unified School District in the Adult Transition program, followed by employment by Casa de Amma in San Juan Capistrano.

Karen was ordained with her husband, Dave, in 2007. They served at three Episcopal churches in the Inland Empire: St. Peter’s, Rialto; St. Luke’s, Fontana; and St. Clare’s, Rancho Cucamonga. In February 2014 Karen was called to St. Wilfrid of York Episcopal Church in Huntington Beach. Karen’s beloved husband, Rev. Dave, went on permanent disability due to an Alzheimer’s diagnosis. He passed away January 6, 2016.

At St. Wilfrid’s, Karen’s areas of responsibility were Pastoral Care and Outreach, with a particular focus as Executive Director of Beach Cities Interfaith Services, a 501c3 organization whose mission is to offer compassionate, faith-based service to all in need.

As St. John’s Associate Vicar, Karen believes her role is to partner with Rev. Christopher, the people of St. John’s, and the church staff to present the Gospel with love, humor and compassion in every encounter, including the greater Rancho Santa Margarita community.

Karen says, ‚ÄúAs a person, my greatest joy is found in relationships; with God, family, friends, and with all people with whom I come in contact. God‚Äôs care for each of us is so deep, so intimate, so filled with compassion and love! My prayer is that, as a priest I might be able in some small way to convey the magnificence and beauty of our loving Triune God.‚ÄĚ

Karen and Dave have two children, Gretchen Killebrew and Michael Maurer. Gretchen has three children Kye, Kalena and Ella. Michael has two children, Vivienne and Jackson. Karen is close to her family members, including her sister JoAnne Sand and her husband Brad; Dave’s brothers Stephen Maurer and his wife Jane, and Larry and his wife Barbara. Many nieces, nephews, grandnieces and grand nephews round out Karen’s extended family.

Karen’s hobbies include daily walks, beach doubles volleyball, reading, swimming, playing music with friends, spending time with family and friends, and entertaining at home.

Youth Pastor Search

Before the next minister to youth comes to serve the people of St. John‚Äôs, Lisa Naulls, a member of the Bishop‚Äôs Committee, has already begun to call together the youth of the¬†parish for a¬†listening session. We invite the youths (middle school, high school, college age, twenty-somethings) for further opportunities to be heard and to convey your wishes and dreams about what the church needs to be for you now, and what it might look like in the future. The ‚Äėelders‚Äô of St. John‚Äôs and I (Rev. Christopher) are aware and excited with how the church is being led to new things, new ways of living the Gospel of Jesus. We recognize that past models of church, of worship, and for gathering are not well-suited for your lifestyle. The voices of young people ‚Äď your voices ‚Äď need to be heard and your hands need to be part of what builds the framework of this evolving church.

Please contact Rev. Christopher right here to express your interest in furthering this holy conversation? We look forward to meeting with you again.

We are most grateful to Patti Peebles who fiercely led the St. John’s Youth Group for many years along with her team of dedicated volunteers, most recently Dave and Mary Nichols, Joe Miramontes, and Mike Olivor. Patti will now serve full time as chaplain for St. John’s School.

Roger Bradshaw, Assistant Church Administrator

Roger joined St. John’s parish in 2010, taking on volunteer roles in the Food Pantry and Men’s ministry before becoming its Assistant Church Administrator in early 2017.

Roger was raised in a non-religious household, never really thinking about the subject until as a newlywed, his wife, Joanne, said that she wanted to find a church home for the two of them. They were baptized together in to the Roman Catholic Church when Roger was 25. They chose the Roman Catholic faith because they were drawn to its traditional liturgy and pageantry.

Being on the School Board of St. George’s Episcopal School in Lake Forest, where his two son’s attended, led Roger to experience his first Episcopal church service in 2002. He and Joanne were already experiencing frustration with the direction of the Roman Catholic Church, so Roger suggested to Joanne that she check out a service at St. George’s too, and they both knew that they had found a new church home with the Episcopal Church. They stayed at St. George’s until a job opportunity took them to France and Denmark for five years. Based on the strength of St. John’s Youth Ministries, they joined St. John’s when they returned in 2010.

Wanting to deepen his knowledge of the Bible, Church history and its place in society, Roger enrolled in the Education for Ministry (EfM) program at St. John’s in 2013, and graduated in 2016. He found the program very rewarding, as it increased his knowledge and understanding of God’s love for all of us, and how to apply that love to his everyday life.

When asked about what he appreciates about St. John‚Äôs, Roger said, ‚ÄúWhat really impresses me about the people of St. John‚Äôs is how active and engaged they are, not only in their faith, but in applying that faith to the issues and problems they see around them. They don‚Äôt wait for permission to tackle a problem or begin a ministry, they just go about doing it.‚ÄĚ

Roger’s hobbies include woodworking and home improvements, working on his old car, and walking his two high-energy dogs with his wife.

Chrissy Hennings, Director of Children’s Ministry

Chrissy and Russ Hennings joined St. John‚Äôs church shortly before their daughter, Acacia, went to school at St. John‚Äôs Episcopal School. They instantly fell in the love with the school and decided to make St. John‚Äôs their church home as well. Chrissy was raised in the Catholic church but felt a strong connection with the Episcopal Church which is the denomination in which Russ was raised. Russ’s father was also an Episcopal priest. St. John‚Äôs has been a truly welcoming place for their family. Chrissy enjoys spending time with her family and friends, cooking, working out, and shopping!

Chrissy began serving as the Director of Children’s Ministries in May 2021.
