True Saints Are Perfectly United in the Same Mind and in the Same Judgment

1 Corinthians 1:10–13

10 Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.
11 For it hath been declared unto me of you, my brethren, by them which are of the house of Chloe, that there are contentions among you.
12 Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.
13 Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?

Elder Bruce R. McConkie wrote:

“Division and dissension, contention, confusion and discord—these are among the prevailing characteristics of the sects of Christendom. These various sects or denominations—all holding to their particular creeds and practices—will never unite, except on one point: all will join hands to fight the truth and stand in opposition to The Church of Jesus Christ of Latter-day Saints [see Joseph Smith—History 1:20–25].

“Existence of the sects of Christendom is proof positive of the universal apostasy. Truth is one; Christ is not divided; those who enjoy the Spirit, all speak the same things; there are no divisions among them; but they are ‘perfectly joined together in the same mind and in the same judgment’ [see 1 Corinthians 1:10–13]. When Joseph Smith retired to the Sacred Grove, it was to ask the Lord which of all the sects was right and which he should join. The answer: ‘I must join none of them, for they were all wrong’ [see Joseph Smith—History 1:14–20].

“But the apostate nature of the creeds and teachings of the sects in no sense means that all sectarians, as individuals, are living in gross unrighteousness without desiring to know and live the truth. ‘There are many yet on the earth among all sects, parties, and denominations,’ the Prophet wrote by way of revelation, ‘who are blinded by the subtle craftiness of men, whereby they lie in wait to deceive, and who are only kept from the truth because they know not where to find it’ [D&C 123:12].”
