So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air. There are, it may be, so many kinds of voices in the world, and none of them is without signification. Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me. 1 Corinthians 14:9-11.
Ministers who labor in word and doctrine should be thorough workmen, and should present the truth in its purity, yet with simplicity. They should feed the flock with clean provender, thoroughly winnowed. There are wandering stars professing to be ministers sent of God who are preaching the Sabbath from place to place, but who have truth mixed up with error and are throwing out their mass of discordant views to the people. Satan has pushed them in to disgust intelligent and sensible unbelievers.
Some of these have much to say upon the gifts and are often especially exercised. They give themselves up to wild, excitable feelings and make unintelligible sounds which they call the gift of tongues, and a certain class seem to be charmed with these strange manifestations. A strange spirit rules with this class, which would bear down and run over anyone who would reprove them. God's Spirit is not in the work and does not attend such workmen. They have another spirit. Still, such preachers have success among a certain class. But this will greatly increase the labor of those servants whom God shall send, who are qualified to present before the people the Sabbath and the gifts in their proper light, and whose influence and example are worthy of imitation.
The truth should be presented in a manner which will make it attractive to the intelligent mind. We are not understood as a people, but are looked upon as poor, weak-minded, low, and degraded. Then how important for all who teach, and all who believe the truth, to be so affected by its sanctifying influence that their consistent, elevated lives shall show unbelievers that they have been deceived in this people. How important that the cause of truth be stripped of everything like a false and fanatical excitement, that the truth may stand upon its own merits, revealing its native purity and exalted character.—Testimonies for the Church 1:414, 415.
