Indeed, one of the chapters of After Virtue is entitled "Nietzsche or Aristotle?"-for moral philosophy boils down to emotivism or teleology.The best thing is that we, as Christians, have a teleology (or in other terms, an eschatology, an end, a purpose, a goal) and thusly a morality. You can find it in the first of Paul's letters to the Corinthians.
But in fact Christ has been raised from the dead, the first fruits of those who have died. For since death came through a human being, the resurrection of the dead has also come through a human being; for as all die in Adam, so all will be made alive in Christ.
When this perishable body puts on imperishability, and this mortal body puts on immortality, then the saying that is written will be fulfilled:‘Death has been swallowed up in victory.’The sting of death is sin, and the power of sin is the law. But thanks be to God, who gives us the victory through our Lord Jesus Christ.
‘Where, O death, is your victory?
Where, O death, is your sting?’
Therefore, my beloved, be steadfast, immovable, always excelling in the work of the Lord, because you know that in the Lord your labour is not in vain.
