605. 'That he give them a mark upon their right hand, and upon their foreheads' signifies that no one is acknowledged as a Reformed Christian unless he receives that doctrine in faith and love. By 'to give a mark' is signified to acknowledge as a Reformed Christian, or as being of the confession that the doctrine teaches. The 'mark' is the acknowledgment that he is such, as also the confession that he is. By 'the right hand' is signified everything of a man as to intellectual power, thus as to faith, for 'the right hand' signifies a man's power (n. 457); by 'the forehead' is signified everything of a man as to will power, thus as to love, for 'the forehead' signifies love (n. 347).
