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.

↑ Return to TopThe Rev. Canon Walter L. Krieger, Priest Associate
Fully
retired after thirty-eight years of active ministry Walter has become
an active and very welcome member of Mediator. With is wife, Judith, he
has worshipped with us on a regular basis.
In his professional ministry he has served parishes in Merchantville and Moorestown, New Jersey, Wooster, Ohio, and Reading, Pennsylvania (where he was rector for twenty-four years). He served on elected and appointed diocesan committees and as a deputy to five General Conventions. He has worked with national and community boards and agencies, and taught in seminary.
Walter says, he is still the kid who likes to listen to the music he grew up with in the fifties, who still savors the sunrises along the beach in Cape May where he grew up, who won't miss a Saturday broadcast of the Metropolitan Opera, who paints all kinds of subject matter and abstracts in watercolor and acrylics, who reads a little French every day, who loves to travel in France, who enjoys a cat in his lap, who takes long walks, who practices God's presence and who finds God's blessing in the ordinary and extraordinary moments of life.
In his retirement years, Walter hopes to expand his practice as a spiritual director and have more opportunities for conducting retreats and workshops, as well as continuing to lead an ecumenical Benedictine fellowship in Reading. Working with children in the city schools is another goal to pursue. There is reading and writing, music and painting to enjoy. There are old relationships to nurture and new ones to anticipate. And, he looks forward to assisting in worship as Maria needs him and to helping with parish programs as he is able.
Walter and his wife make their home in Reading. Judith is a professional artist, teaching five classes a week, painting, exhibiting, and leading painting holidays abroad. Their children, Rachel and Joel live in Allentown and are now members of Mediator as well.
