Every time we say the Creed at Communion or Baptism we are affirming Paul’s declaration and the teaching of the earliest church in the resurrection of the body. This doctrine of the Church causes many real problems because they cannot envisage what having a body after death means especially now most people are cremated.
Paul was dealing with an argument that had emerged in the Corinthian Church with some denying the reality of resurrection. The immortality of the soul was as popular then as it is now.
Paul was clear in his thinking: without resurrection of the body the faith is pointless. Christ rose from the dead and so his followers will in time. How exactly we will look is not known but we will be raised and according to Paul “the perishable must clothe itself with the imperishable, and the mortal with immortality.”
Our faith is not a moral code but a living dynamic belief that God made us special and we will enjoy the particular status beyond this life. In the resurrection of the body the Church affirms we believe not even death can thwart the purposes of God.
