Over here in Asia, some of us are thrilled that a General Authority could deliver his talk in Cantonese (see the news story at the Salt Lake Tribune). Elder Chi Hong (Sam) Wong made history as he gave the first General Conference sermon in a language other than English. We had the pleasure of meeting him a while ago in Shanghai–very kind and interesting man. Later Elder Eduardo Gavarret gave his talk in Spanish. Awesome!
I look forward to hearing some talks in Mandarin in the future.
English will continue to dominate the leadership of the Church, but it may become a minority language among Mormon leaders in the future.
Which reminds me, this would be a good time for more of you to start studying Mandarin. Great for your own personal enrichment, great for business, and great for communicating with so much of the world. Just a suggestion, one that President Kimball himself made a few decades ago.
