In a letter to priesthood leaders, the First Presidency announced the addition of "virtue" to the Young Women theme. The letter read, in part, "We are pleased to announce the addition of the attribute of "virtue" to the Young Women theme. This addition will assist young women in developing high moral standards. We invite parents and leaders to teach the doctrine of chastity and moral purity to help each young woman to be virtuous and worthy to make and keep sacred covenants and receive the ordinances of the temple."
