Four Way Medals are a unique style of Catholic Jewelry. Instead of being a representation of a specific saint or medal the four way medal contains multiple saints.
First, the medal is shaped like a cross. Each arm of the cross contains a representation of the Sacred Heart, the Miraculous Medal, St. Christopher and St. Joseph. The back of the cross contains images of Our Lady of Mt. Carmel and the back of the Miraculous Medal. Typically the medal also has the words "I am a Catholic, please call a priest." on the back.
Sometimes a four way medal has an additional symbol at its center such as the Holy Spirit or a chalice for First Communion. These medals are sometimes referred to as five way medals.
