Elder Quentin L. Cook of the Quorum of the Twelve Apostles was born on Sept. 8, 1940, in Logan, Utah. He has served as an Apostle since Oct. 6, 2007, when he was called to fill the vacancy in the Quorum created when President Henry B. Eyring was called to the First Presidency following the death of President James E. Faust, a counselor to President Gordon B. Hinckley.
In a news conference following his call as an Apostle, Elder Cook said: “As you know in the Church, we neither seek calls or have any expectation ever that a call will come to us, and I certainly had no idea I’d be receiving this call. Neither do we turn down a call particularly when it comes from a faithful loving Prophet who is so dear to us. And so I accept that call and pledge to do everything that I possibly can to be worthy and accomplish what the Lord would have me accomplish.”
Elder Cook served as a young full-time missionary in the British Mission and married Mary Gaddie in the Logan Utah Temple on Nov. 30, 1962. They have three children.
He previously served in the Philippines Area presidency, as president of the Pacific and North America Northwest areas and as executive director of the Missionary Department.
In honor of his 86th birthday, here are nine of his quotes from the past year.
