As Latter-day Saints we know that right is adherence to God’s laws and wrong is anything contrary to those laws.
To give an example: Commandments are a form of God’s law. One of the 10 Commandments given to Moses in the 20th chapter of Exodus is “Thou shalt not steal.” When a person steals from another person we know that is wrong. How do we know? Because it is contrary to the law that God has given us.
This concept of right vs. wrong and good vs. evil is essential in understanding homosexuality as it relates to members of the Church of Jesus Christ of Latter-day Saints, as well as all people everywhere.
