Not all the Brethren have been businessmen, but most have had extraordinarily successful careers by the time they are called to be an Apostle. As President Spencer W. Kimball once pointed out, the ability to lead people and an organization is a more-than-helpful attribute in a Church of millions of people, especially when combined with spiritual depth and a rich understanding of the gospel.
Can a member be a Democrat and a good Mormon? That one makes me smile, because if the members who ask it could travel to some countries of the world and meet faithful members of the Church who belong to their national communist parties I fear their blood pressure might be permanently damaged.
While I love the diversity in the Church, I don’t believe that ultimately diversity trumps unity. “If ye are not one, ye are not mine.”
If all we ever play is a defensive game, the most we can hope for is a draw.
At the same time, the Church from ancient times has essentially been counter-cultural, which means that it often pushed back against social conventions and established institutions. Jesus talked a lot about sheep, but he never acted like one. He challenged social norms, associated with people who polite society rejected, and confronted the establishment when it displayed hypocrisy. The apostles, too, fearlessly challenged convention time after time in order to teach gospel truths.
There is a strong tendency today for many to talk of Jesus Christ as if His teachings on love were somehow inconsistent with his teachings on divine commandments. Of course the Savior’s love was never withheld from anyone and His words on the cross exemplify that. But, He also expressed love by teaching clear doctrine and standing firmly against sin with sometimes-tough lessons for which people rejected Him.
