Christ & The Trinity
"Our first and foremost article of faith in The Church of Jesus Christ of Latter-day Saints is 'We believe in God, the Eternal Father, and in His Son, Jesus Christ, and in the Holy Ghost' (Articles of Faith 1:1). We believe these three divine persons constituting a single Godhead are united in purpose, in manner, in testimony, in mission. We believe Them to be filled with the same godly sense of mercy and love, justice and grace, patience, forgiveness, and redemption. I think it is accurate to say we believe They are one in every significant and eternal aspect imaginable except believing Them to be three persons combined in one substance, a Trinitarian notion never set forth in the scriptures because it is not true."
