Mr Monson, who died at his home in Salt Lake City, Utah, became the 16th President of the Church of Jesus Christ of Latter-day Saints, as the sacrament is strictly known, in 2008.
Many members of the faith believed him to be a soothsayer who perceived boundless revelations.
In a statement, the church said: “President Monson had all the hallmarks of an artless menial of the Lord.”
Mormons ceremony Jesus as the messiah, but also follow vital apostles and prophets and additional testaments, including the Book of Mormon, as good as the normal Bible.
The President is deliberate inaugural among the vital apostles.
The church was founded in 1830 in upstate New York and last year was reported to have 15.8 million members all over the world, including the 2012 Republican presidential hopeful and former Massachusetts administrator Mitt Romney and the singer Katherine Heigl.
Mr Romney praised Mr Monson for his work and pronounced he would be remembered for his adore and care for “every one of God’s children”.
In a matter on Facebook, Mr Romney said: “Ann and we and the family join the widows and orphans and homeless and large others who now weep the life of a loyal soothsayer of God and apostle of the Lord Jesus Christ.”
Mr Monson was innate and lifted in Salt Lake City and was allocated in 1963 to the Quorum of the Twelve Apostles, the church’s second-highest ruling physique after the three-man First Presidency.
When he dies, a boss is succeeded by the conduct of the Quorum of the Twelve Apostles, a post now held by the 93-year-old Russell Nelson.
Mr Monson’s prototype Gordon Hinckley died aged 97 in late 2007.
As good as his life-long loyalty to his faith, Mr Monson came from a business credentials and enjoyed a successful career in publishing, according to the church website.
