Highlights:

"Our tolerance and respect for others and their beliefs does not cause us to abandon our commitment to the truths we understand and the covenants we have made. That is a third absolute truth. We are cast as combatants in the war between truth and error. There is no middle ground. We must stand up for truth, even while we practice tolerance and respect for beliefs and ideas different from our own and for the people who hold them."

"Our obligation to tolerance means that none of these behaviors—or others we consider deviations from the truth—should ever cause us to react with hateful communications or unkind actions. But our obligation to truth has its own set of requirements and its own set of blessings."

"[W]hen believers promote their positions in the public square, they should always be tolerant of the opinions and positions of those who do not share their beliefs. Believers must always speak with love and show patience, understanding, and compassion toward their adversaries."
