Let us remember, that we live in a world where Pharisaism and Sadduceeism are continually striving for the mastery in the Church of Christ. Some want to add to the Gospel, and some want to take away from it. Some would bury it, and some would pare it down to nothing. Some would stifle it by heaping on additions, and some would bleed it to death by subtraction from its truths. Both parties agree only in one respect. Both would kill and destroy the life of Christianity, if they succeeded in having their own way. Against both errors let us watch and pray, and stand upon our guard. Let us not add to the Gospel, to please the Roman Catholic Pharisee. Let us not subtract from the Gospel, to please the Neologian Sadducee. Let our principle be “the truth, the whole truth, and nothing but the truth,” nothing added to it, and nothing taken away.
