A spirit of fanaticism has ruled a certain class of Sabbathkeepers there; they have sipped but lightly at the fountain of truth and are unacquainted with the spirit of the message of the third angel.... NL 49.2
Some of these persons have exercises which they call gifts and say that the Lord has placed them in the church. They have an unmeaning gibberish which they call the unknown tongue, which is unknown not only by man but by the Lord and all heaven. Such gifts are manufactured by men and women, aided by the great deceiver. Fanaticism, false excitement, false talking in tongues, and noisy exercises have been considered gifts which God has placed in the church. Some have been deceived here.... NL 49.3
Fanaticism and noise have been considered special evidences of faith. Some are not satisfied with a meeting unless they have a powerful and happy time. They work for this and get up an excitement of feeling. NL 49.4
But the influence of such meetings is not beneficial. When the happy flight of feeling is gone, they sink lower than before the meeting because their happiness did not come from the right source. The most profitable meetings for spiritual advancement are those which are characterized with solemnity and deep searching of heart; each seeking to know himself, and earnestly, and in deep humility, seeking to learn of Christ.... NL 50.1
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. [Testimonies for the Church 1:411-414.] NL 50.2
The world will not be converted by the gift of tongues, or by the working of miracles, but by preaching Christ crucified. [Testimonies to Ministers and Gospel Workers, 424.] NL 50.3
