The Lord defined some very basic differences between men and women. He gave the male what we call masculine traits and the female feminine traits. He did not intend either of the sexes to adopt the other's traits but, rather, that men should look and act like men and that women should look and act like women. When these differences are ignored, an unwholesome relationship develops, which, if not checked, can lead to the reprehensible, tragic sin of homosexuality. In other words, we have a responsibility as priesthood bearers to be examples of true manhood.
"The Meaning of Morality" Victor L. Brown, 1971 General Conference
It is most important that you Aaronic Priesthood holders learn what strengths you have as men. Possibly you were foreordained to great priesthood callings. You need to learn that these masculine strengths are great, noble, and God-given; however, they also have some limitations. Because of these limitations, it is equally important to learn how the influence of good women in our lives can complement these strengths and overcome these limitations. As you walk on the way to eternity, it is important to gain some understanding and appreciation for the wonderful endowments and callings God has given uniquely to women. I wonder if we really understand the fulness of these queenly endowments.
"The Highest Place of Honor", James E. Faust 1988 General Conference
Some roles are best suited to the masculine nature and others to the feminine nature.
Boyd K. Packer, 1993
Be careful lest you unknowingly foster influences and activities which tend to erase the masculine and feminine differences nature has established. ...Even so, leaders, and especially parents, should recognize that there is a distinct masculine nature and a distinct feminine nature essential to the foundation of the home and the family. Whatever disturbs or weakens or tends to erase that difference erodes the family and reduces the probability of happiness for all concerned.
Boyd K. Packer, 1998 General Conference
