President Nelson participated in meetings and other duties at the Church Administration Building on Temple Square, according to ChurchofJesusChrist.org.
Born Sept. 9, 1924, in Salt Lake City, he became the oldest President in Church history earlier this year, on April 14.
He expressed appreciation for the many cards and well-wishes he received for his birthday.
Of President Nelson’s life and service, President Dallin H. Oaks, first counselor in the First Presidency, said: “He is an inspired and wise leader and the gentlest and sweetest person you could ever hope to associate with.”
Added President Henry B. Eyring, second counselor: “Every time we walk out of the office, President Oaks and I say, ‘It happened again.’ You’ll just see revelation come. You’ll see him ask for counsel, and then the decision will come, and everybody in the room knows it is right and from God. He just quietly says, ‘I think this is what the Lord would want us to do.’ It’s just time after time.”
