“All who are baptized into the name of the Father, and of the Son, and of the Holy Ghost, recognizing the Trinity of Persons in the Godhead, the incarnation of the Son and his priestly sacrifice, whether they be Greeks, or Arminians, or Romanists, or Lutherans, or Calvinists, or the simple souls who do not know what to call themselves, are our brethren. Baptism is our common countersign. It is the common rallying standard at the head of our several columns.”
A.A. Hodge, Evangelical Theology (Carlisle, PA: Banner of Truth,1976), p. 338.
