I found this interesting passage concerning “spiritual gifts”:
[W]hen people turn to Christ, and receive the Spirit, their whole life becomes pneumatic. In the terms of Romans 8 and Galatians 5-6, all authentic Christian existence is ‘led by the Spirit’, bears the ‘fruit of the Spirit’, and is empowered by the Spirit. There is thus a sense in which all Christian life is the gift of the Spirit, the charisma of God expressed in a multitude of charismata. This is undoubtedly one of the reasons why it is difficult to provide from Paul a sharply defined class of ‘spiritual gifts’…. So asking the question ‘at what point does this or that activity of the Spirit become a “spiritual gift”?’ is like asking how many hairs a man must lose before he becomes ‘bald’. (M. Turner, “Spiritual gifts,” in New Dictionary of Biblical Theology (ed. T. Desmond Alexander and Brian S. Rosner; Downers Grove: IVP, 2000), p. 794) (italics in original)
Do we need a “sharply defined class of spiritual gifts”? Why do you think Paul (and Peter) always gave different lists of spiritual gifts? What would be the danger is seeing any activity that is led/empowered by the Spirit as a “spiritual gift”?
