380. Is the visible side of the church of Jesus Christ perfect?

No, the visible side of the church of Jesus Christ is not perfect. After all, the people at work within it did not always show the love, compassion, truthfulness, and kindness of Jesus.
The church is run by sinful human beings who are prone to error. It is for this reason that the same mistakes, deficiencies, and blunders inherent in mankind are also to be found in the church.
It is here that the visible side of the church fundamentally differs from the human nature of Jesus. In contrast to the visible side of the church, which is deficient, Jesus Christ was also perfect and sinless in His human nature.
