Accomplishing the Father's Plan (1066-1067)
The Creed outlines the Trinity's work. The Father gives his Son and his Spirit to accomplish his "plan of mystery" (Eph 3:9). This is "the economy of salvation."
God's Old Testament works were a prelude to Christ's redemption of mankind, a work accomplished by his death, Resurrection, and Ascension. "Dying he destroyed our death, rising he restored our life."
