St Matthew Orthodox Church
Green Bay, Wisconsin
Sister Bay
Holy Transfiguration Chapel, Sister Bay, Door County Wisconsin, can serve you as your “home away from home.”

Always open, the Chapel is available day and night. Many visitors and others have found the Chapel to be a special place “apart,” dropping in to pray, light a candle, attend a Service, or just to be quiet before God. Additionally, the visitor finds an extensive lending library and informative tracts.

The Chapel is a functioning part of the St. Matthew Orthodox Church of Green Bay, Wisconsin, and is served and maintained by Reader George (“Pat”) Mangan, A.I.A, a long-time resident of Sister Bay, who designed and built the Chapel as an outpost of Orthodoxy in Door County.  It is located in the woods at 10764 N. Bayshore Drive in Sister Bay. Pat can be reached at (920) 854-4215, or

Some of you are visiting from countries where Orthodox Christianity has been for centuries— where Orthodox churches are numerous and where Orthodox believers are many.   While there are 250 million orthodox Christians worldwide, here you will find that the wonderful heritage we share with them is yet to be fully discovered.  You can be a good witness to the fullness of your unchanging apostolic faith by simply living it here as you do in your home country. Hold fast to what you have been taught.  Please invite others to “come and see” the Way you follow Christ.  You are also encouraged to seek out and fellowship with others who use the Chapel for their private and personal prayers, and to participate in the monthly services. 

Many of the icons are donations to the Chapel by those who came before you.  You are also welcome to help with maintenance as you see needed to keep the Chapel area presentable.

Holy Orthodoxy was planted in America by missionaries only a little over 200 years ago. The Orthodox Church in America welcomes you, and, under the archpastoral direction of His Grace, Bishop Paul, Diocese of the Midwest, will be providing the ministrations of a priest.  Check our ad in the Door Reminder, and at the Chapel, or call (920) 854-4215 for Service dates and times.

The Holy Scripture is a collection of books written over multiple centuries by those inspired by God to do so. It is the primary witness to the Orthodox Christian faith, within Holy Tradition and often described as its highest point. It was written by the prophets and apostles in human language, inspired by the Holy Spirit, and collected, edited, and canonized by the Church.

Holiness or sainthood is a gift (charisma) given by God to man, through the Holy Spirit. Man's effort to become a participant in the life of divine holiness is indispensable, but sanctification itself is the work of the Holy Trinity, especially through the sanctifying power of Jesus Christ, who was incarnate, suffered crucifixion, and rose from the dead, in order to lead us to the life of holiness, through the communion with the Holy Spirit.
