Another fine post by Dr. Witherington, who, like Tom Wright, is not afraid to use his God-given faculties to wrestle with issues of faith and life. Worth your time to read.
You will notice that ‘critical thinking’ often comes up in the context of persons trying to decide what to believe and what not to believe. Unfortunately, ‘critical thinking’ has sometimes gotten a bad name, especially in very conservative Protestant circles because it is associated with people negatively assessing or even criticizing the Bible. This is unfortunate on various grounds.
