branch of Christian theology that defends Christianity against objections
Christian apologetics (Greek: ἀπολογία, "verbal defence, speech in defence") is a branch of Christian theology that defends Christianity against objections.Christian apologetics has taken many forms over the centuries, starting with Paul the Apostle in the early church and Patristic writers such as Origen, Augustine of Hippo, Justin Martyr and Tertullian, then continuing with writers such as Thomas Aquinas, Duns Scotus, William of Ockham and Anselm of Canterbury during Scholasticism.
Blaise Pascal was an active Christian apologist before the Age of Enlightenment. In the modern period, Christianity was defended through the efforts of many authors such as G. K. Chesterton and C. S. Lewis, as well as G. E. M. Anscombe.
In contemporary times, Christianity is defended through the work of figures such as Norman Geisler, Robert Barron, Scott Hahn, John Lennox, Lee Strobel, Francis Collins, Alvin Plantinga, Hugh Ross, James White, Gary Habermas, Frank Turek, R. C. Sproul, Ravi Zacharias,
Eric Mason and William Lane Craig.
