The Seven Marks Society is Evangelical Catholic Lutherans associated with Lutheran CORE who approach the Common Confession through the lens of Martin Luther's Seven Marks of the Church:

       * the Holy Word of God
       * Holy Baptism
       * Holy Communion
       * Holy Absolution
       * the Holy Ministry
       * Public Prayer
       * the Holy Cross

Where you find these, you find the One, Holy, Catholic, and Apostolic Church.
