The Bible
Mosiah 15
How Christ is both the Father and the Son—He will make intercession and bear the transgressions of His people—They and all the holy prophets are His seed—He brings to pass the Resurrection—Little children have eternal life. About 148 B.C.
4And they are one God, yea, the very Eternal Father of heaven and of earth.
15And O how beautiful upon the mountains were their feet!
16And again, how beautiful upon the mountains are the feet of those that are still publishing peace!
