The Rev. Canon Maria W. E. Tjeltveit, Rector
The Reverend Canon Maria W. E. Tjeltveit is the rector of The Episcopal Church of the Mediator, having begun her ministry on September 1, 1999. (Her first name is pronounced "Mariah" and her last name is pronounced "Chelt vate".)
Maria is a member of the Moravian-Episcopal dialogue on the national level and is active in Jewish-Christian and Muslim-Christian dialogue. She has been appointed by the Bishop to be the Ecumenical and Interfaith Officer for the Diocese of Bethlehem. She graduated from Swarthmore College and the Berkeley/Yale Divinity School. Before coming to Mediator, she served at St. Matthew's Episcopal Church in Charleston, West Virginia; St Paul's Episcopal Church in Alexandria, Virginia; and St. Andrew's Episcopal Church in Harrington Park, New Jersey.
Maria, her husband Dr. Alan Tjeltveit, who is a Professor in Psychology at Muhlenberg College, and their children, William and Anna, live in Allentown.
You can reach her at the church by phone (610) 434-0155 and by email at firstname.lastname@example.org. Her day off is Friday.↑ Return to Top
The Rev. Twila Smith, Missioner for Growth
A recent graduate of the Church Divinity School of the Pacific in Berkeley, Twila was ordained to the priesthood in the Diocese of Oklahoma in August 2014, just before beginning her role with Mediator. She is nourished in common life as a life-professed member of a non-residential religious community of men and women, following the work of St. David Pendleton Oakerhater in ministries of reconciliation.
While in San Francisco, Twila served at St. Aidan's, a mission-focused parish engaged in its neighborhood and surrounding community, and was the missioner for the Celtic Cross Society at the seminary, funding small-dollar grants and engaging the community in hands-on mission. In the summer of 2013 she went on a 30-day, 490-mile pilgrimage around the San Francisco Bay, visiting 70 Episcopal churches, and exploring the sacredness that is in our midst. She has trained and worked in community outreach and development, and building neighborhood partnerships, particularly in multicultural environments.
Twila stands "always and everywhere" due to a spine issue - and says she has never found that God needs her to sit to be able to serve. She delights in cooking and feasting with friends and strangers, and continues to fall more in love with God and the church. ↑ Return to Top

Liz Hersh, Missioner for Children and Youth
Liz has been involved with Sunday School at Mediator for many years, moving from Vestry Christian Education liaison to Sunday School teacher. Unlike some people who become stale when they do something for a long time, Liz is continually looking for ways to renew and improve our ministry to children and youth. She researched, trained for, and implemented the Catechesis of the Good Shepherd Level 1 at Mediator over a decade ago. In the last couple of years, Liz expanded Catechesis to the early elementary level. She got the extensive training needed for Catechesis of the Good Shepherd Level 2 and has worked hard to create our True Vine Atrium for ages first through third graders.
While Liz’s ministry has focused on Sunday School, her husband, Joe, is a J2A mentor, and her sons, Chris and Adam, both went through the full Journey to Adulthood program. So she is familiar with the range of our children and youth ministry.
Outside of Mediator, Liz earned her Bachelor of Science degree in Nursing from Cedar Crest College in 1979. At present. Liz works part-time at The Village Preschool, in Zionsville, keeps the books for Joe’s handyman business, and works with Bill Korp, our bookkeeper in his accounting business. In the community, she is active in the Boy Scouts of America serving on the committee for Boy Scout Troop 70 in Emmaus. Return to Top
