Elder Holland, 2007, PBS interview for 'The Mormons':
PBS: [You say] there are stark choices in beliefs about the origins of the book. Explain why there's no middle way.

Elder Holland: ... If someone can find something in the Book of Mormon, anything that they love or respond to or find dear, I applaud that and say more power to you. That's what I find, too. And that should not in any way discount somebody's liking a passage here or a passage there or the whole idea of the book, but not agreeing to its origin, its divinity. ...

I think you'd be as aware as I am that that we have many people who are members of the church who do not have some burning conviction as to its origins, who have some other feeling about it that is not as committed to foundational statements and the premises of Mormonism. But we're not going to invite somebody out of the church over that any more than we would anything else about degrees of belief or steps of hope or steps of conviction. ... We would say: "This is the way I see it, and this is the faith I have; this is the foundation on which I'm going forward. If I can help you work toward that I'd be glad to, but I don't love you less; I don't distance you more; I don't say you're unacceptable to me as a person or even as a Latter-day Saint if you can't make that step or move to the beat of that drum." ... We really don't want to sound smug. We don't want to seem uncompromising and insensitive.

In this Church our wards and our quorums do not belong to us. They belong to Jesus Christ. Whoever enters our meetinghouses should feel at home. The responsibility to welcome everyone has growing importance. The world in which we live is going through a period of great upheaval. Because of the increased availability of transportation, speed of communication, and globalization of economies, the earth is becoming one large village where people and nations meet, connect, and intermingle like never before.

These vast, worldwide changes serve the designs of Almighty God. The gathering of His elect from the four corners of the earth is taking place not only by sending missionaries to faraway countries but also with the arrival of people from other areas into our own cities and neighborhoods. Many, without knowing it, are being led by the Lord to places where they can hear the gospel and come into His fold.

It is very likely that the next person converted to the gospel in your ward will be someone who does not come from your usual circle of friends and acquaintances. You may note this by his or her appearance, language, manner of dress, or color of skin. This person may have grown up in another religion, with a different background or a different lifestyle.

But while the Atonement is meant to help us all become more like Christ, it is not meant to make us all the same. Sometimes we confuse differences in personality with sin. We can even make the mistake of thinking that because someone is different from us, it must mean they are not pleasing to God. This line of thinking leads some to believe that the Church wants to create every member from a single mold—that each one should look, feel, think, and behave like every other. This would contradict the genius of God, who created every man different from his brother, every son different from his father. Even identical twins are not identical in their personalities and spiritual identities. It also contradicts the intent and purpose of the Church of Jesus Christ, which acknowledges and protects the moral agency—with all its far-reaching consequences—of each and every one of God’s children. As disciples of Jesus Christ, we are united in our testimony of the restored gospel and our commitment to keep God’s commandments. But we are diverse in our cultural, social, and political preferences.

I can quote scripture, I can try to expound doctrine, and I will even quote a bumper sticker I recently saw. It was attached to the back of a car whose driver appeared to be a little rough around the edges, but the words on the sticker taught an insightful lesson. It read, “Don’t judge me because I sin differently than you.”

Any religious group that values purity and morality must deal with the problem of clannishness. However, clannishness can be largely avoided if the members of the group have a vigorous concern to share. There is a big difference between reaching out and shutting out—and Jesus steadily opposed every hint of the latter.

In a journal entry where Orson Hyde is complaining about black people's aspirations, Joseph replies:

If I raised you to be my equal & then attempt to oppress you, would you not be indignant?

"As I grew up in Europe following the Second World War, the political system then was symbolized by a single word—division—and by a name and a location—the Berlin Wall. It was the Cold War system... in a broad sense, we have come from a world of division and walls to a system built increasingly around integration. This type of globalization is bringing the world closer together. Borders are coming down, and the rewards will be measured in better standards of living, less poverty around the world, more respect and deference for diversity of culture, and peace for all mankind. I believe we all agree that we still have a long way to go."

The Saints can testify whether I am willing to lay down my life for my brethren. If it has been demonstrated that I have been willing to die for a ‘Mormon,’ I am bold to declare before Heaven that I am just as ready to die in defending the rights of a Presbyterian, a Baptist, or a good man of any other denomination; for the same principle which would trample upon the rights of the Latter-day Saints would trample upon the rights of the Roman Catholics, or of any other denomination who may be unpopular and too weak to defend themselves.

"We believe there is a spiritual influence that emanates from the presence of God to fill the immensity of space. (See D&C 88:12.) All men share an inheritance of divine light. God operates among his children in all nations, and those who seek God are entitled to further light and knowledge, regardless of their race, nationality, or cultural traditions."

"The being that has comparatively no strong passion to overcome ought constantly to walk in the vale of humility, rather than boast of his righteousness over his brother... Those who have not strong passions to contend with, day by day, and year by year, should walk in the vale of humiliation; and if brethren and sisters are overtaken in fault, your hearts should be filled with kindness—with brotherly, angelic feeling—to overlook their faults as far as possible."

"There is one principle I wish to urge upon the Saints in a way that it may remain with them—that is, to understand men and women as they are, and not understand them as you are."

"Unity is not achieved by ignoring and isolating members who seem to be different or weaker and only associating with people who are like us. On the contrary, unity is gained by welcoming and serving those who are new and who have particular needs. These members are a blessing for the Church and provide us with opportunities to serve our neighbors and thus purify our own hearts."

The Church thrives when we take advantage of this diversity and encourage each other to develop and use our talents to lift and strengthen our fellow disciples. -
