When the invitation to deliver these lectures came, it was probably intended that they should discuss the attitude of present day Christian teachers towards those of other religions. This, however, seemed fruitless. The attitude of Christian teachers to-day towards their brothers who do not know the Father is practically determined by the individual's apprehension of the Message he is sent to deliver. The one who understands that it is a Message from the One Father to His children everywhere will approach other teachers as brother draws near to brother. The one who regards the Gospel as a system opposing other systems and therefore to be defended, will of necessity deal with others as with antagonists. Hence the only discussion that seemed worthwhile was the essential difference between the Revelation and the religions with a view to determining what obligation this difference lays upon Christian people towards those who know nothing about the Revelation.
