PROVO — Brigham Young University President Cecil Samuelson called this the "Year of the Constitution" at the school Tuesday during the opening devotional of the fall semester.

Speaking on the sixth anniversary of the Sept. 11 attacks, Samuelson encouraged all BYU students to read a book already assigned to incoming freshmen over the summer — "The Words We Live By: Your Annotated Guide to the Constitution," by Linda R. Monk.

The selection of the book was connected to the topic for the devotional and to the scheduled campus visits of three national dignitaries in October and November, when BYU will host U.S. Supreme Court Chief Justice John Roberts, U.S. Senate Majority Leader Harry Reid and bestselling historian Nathaniel Philbrick.

Samuelson's wife, Sharon, also spoke and recommended that students read "1776," by historian David McCullough. McCullough is in Utah today to deliver the keynote address when President Gordon B. Hinckley of The Church of Jesus Christ of Latter-day Saints is awarded the Municipal Citizen of the Year Award by the Utah League of Cities and Towns.

"Please take advantage of the unique opportunity we will all have this year to learn, understand and appreciate (the Constitution) more," President Samuelson said.

The Samuelsons told students that Joseph Smith, founder of the LDS Church, which owns BYU, once said, "I am the greatest advocate of the Constitution of the United States there is on earth" and prayed at the dedication of the Kirtland, Ohio, temple that it would "be established forever."

They also reminded the 5,539 gathered in the Marriott Center that LDS scriptures assert that Jesus Christ raised up the Founding Fathers to establish the Constitution so the church could be organized in the United States in 1830.

"Think what might have been the result," Sharon Samuelson said, "if there had not been freedom of religion, freedom of speech and freedom of assembly expressly guaranteed. While not everyone in the 1830s necessarily believed fully in the freedom of religion, it nevertheless was the law of the land."

The U.S. Constitution was the first written constitution in the world, President Samuelson said, quoting Elder Dallin H. Oaks of the church's Quorum of the Twelve.

"Frequently copied, it has become the United States' most important export," Elder Oaks said. "After two centuries, every nation in the world except six have adopted written constitutions, and the U.S. Constitution was the model for all of them."

This is the first time BYU has asked all incoming freshmen to read a book, said Steve Turley, associate dean of the Office of First-Year Experience.
