A gradual distinction developed between traditional Methodists and the newer Keswick speakers. Keswick took on a more Calvinistic tone, as Keswick preachers took pains to distance themselves from the Wesleyan doctrine of eradication (the doctrine that original sin could be completely extinguished from the Christian soul prior to death). Keswick speakers began using the term "counteraction" to describe the Holy Spirit's effect on original sin, often comparing it to how air pressure counteracts gravity in lifting an airplane. Modern Wesleyan-Arminian theologians regard the Keswick theology as something different from their own dogma of entire sanctification.
