Today, the need for sound apologetics has arguably never been greater. RZIM Zacharias Trust exists to defend the Christian faith against such criticism, on both a popular and an academic level, offering a counter-claim to modern-day secularism. Our apologetics speaking team is complemented by our lecturers and tutors at the Oxford Centre for Christian Apologetics (OCCA), all of whom act as additional speaking resources for the trust, wherever possible. This combined team comprise some of the leading Christian thinkers of our time, with more than 150 years’ speaking and preaching experience between them.
