Comparative analysis of Christian Theologians


1. Shared Features (What They Have in Common)

AspectExplanation
ChristocentrismNearly all theologians (e.g., Augustine, Calvin, Barth, Balthasar, Moltmann) centre theology on Jesus Christ, though differing in emphasis (ontological, experiential, political).
Biblical EngagementAll deeply engage with Scripture, though some (e.g., Luther, Calvin) focus on sola scriptura, while others (e.g., Schleiermacher, Gutiérrez) approach it through experience or justice.
Doctrine DevelopmentEach theologian contributes to the clarification or expansion of Christian doctrines—whether Trinity (Athanasius, Gregory), grace (Augustine, Aquinas), or eschatology (Moltmann).
Cultural EngagementMany responded to their context (e.g., Barth to Nazism, Bonhoeffer to discipleship under tyranny, Gutiérrez to poverty, Schleiermacher to modernity).
Legacy in Their TraditionEach left a lasting impact in their respective tradition (e.g., Aquinas in Catholic scholasticism, Wesley in Methodism, Calvin in Reformed theology).

6. Final Observations

  • Continuity: Across 20 theologians, Christ remains central, even as methods shift—from metaphysics to mysticism, from orthodoxy to praxis.
  • Dialogue Across Time: Many later thinkers (Barth, Moltmann, Balthasar) explicitly engage or revise earlier doctrines (e.g., of Augustine, Aquinas).
  • Geographical Spread: Western dominance in Vol. 1 gives way to global contexts in Vol. 2—Latin America (Gutiérrez), Eastern Orthodoxy (Maximus, Gregory), and German post-war theology (Moltmann).
  • Movement of Theology: From doctrinal defence (Irenaeus) → Scholasticism (Aquinas) → Reform (Luther, Calvin) → Modernity (Schleiermacher) → Response to crisis (Barth, Moltmann) → Liberation (Gutiérrez).
