D&C 50

During the Savior's ministry, it is clear that what He condemned was hypocrisy.  In the early days of the Church, He again emphasized -

"Behold, I, the Lord, have looked upon you, and have seen abominations in the church that profess my name.
5 But blessed are they who are faithful and endure, whether in life or in death, for they shall inherit eternal life.
6 But wo unto them that are deceivers and hypocrites, for, thus saith the Lord, I will bring them to judgment.
7 Behold, verily I say unto you, there are hypocrites among you, who have deceived some, which has given the adversary power; but behold such shall be reclaimed;
8 But the hypocrites shall be detected and shall be cut off, either in life or in death, even as I will; and wo unto them who are cut off from my church, for the same are overcome of the world."  (Doctrine and Covenants 50:4–8)

Obviously, in verse 7, hypocrites can have great affect in offending those whose testimony is still developing.
