Came across this piece today, “A Christmas question: Are the Gospels more reliable than scholars once thought?” And the answer is a resounding yes! The Gospels, and the Bible in general, have been under attack since forever, but especially since German Higher Criticism in the 19th Century, which a priori ruled out any supernatural input to the biblical text. Secular critics presuppose the Bible is a completely human document, so can’t come to the text in anything approaching objective analysis. Yet just like in science, the more that is learned the more credible the biblical sources become.
There are many resources to build a foundation of confidence in the biblical text, but a couple that are worth having easy access to are Michael J. Kruger’s website, Canon Foder. Another scholar to be aware of is Daniel B. Wallace, professor of New Testament Studies at Dallas Theological Seminary. He is also the founder and executive director of the Center for the Study of New Testament Manuscripts, the purpose of which is digitizing all known Greek manuscripts of the New Testament via digital photographs.
Christians have an embarrassment of riches in all kinds of apologetics resources today, and it is well worth building confidence in the book we stake our life and eternity on. God has made that abundantly possible.
