Catholics believe that humans "are created to be one with God forever," he said, that they are capable of sinning, and that God restored humanity to a "right relationship with him" by sending his son Jesus Christ to suffer, die and be resurrected.
As part of the church's teachings, Wester said, Catholics maintain that marriage is between a man and a woman, a belief that the church has a "right to say so" publicly.
Mormons have a different understanding, he said, of human nature, the nature of God and scripture.
But Latter-day Saints and Catholics share a belief in the centrality of Christ and the efficacy of prayer, that humans are expected to be good stewards of the Earth, and, Wester said, that family life and Christian marriage are "not open to fads or new conventions."
Both faiths have been at the forefront in the fight against same-sex marriage.
Together, they also heed the call to help the poor and needy.
Wester noted that before Thomas S. Monson became LDS Church president in 2008, he attended every fundraising dinner for Catholic Community Services. Monson even did so, the bishop said, the week he ascended to the helm of the Utah-based Church of Jesus Christ of Latter-day Saints.
The way the two churches come together, Wester said, "could be a model [for the rest of the nation] of working for the common good."
Debra Hernandez, a Catholic student, liked hearing her bishop spell out her faith for Mormons.
Michelle Gifford, a Mormon student, "felt [Wester's] spirit and love for the LDS community."
Later, UVU President Matthew Holland said the Catholic leader's address was part of the school's effort to be "an inclusive institution." He also announced the creation of an "ecumenical reflection center" in the new student life building going up on campus.
