Defensive apologetics is a branch of Christian apologetics focused on defending the faith against objections and criticisms. It aims to provide rational explanations and evidence for the beliefs held within Christianity, addressing questions about the existence of God, the reliability of the Bible, and the validity of Christian doctrines. Practitioners of defensive apologetics often engage in debates, write articles, and give lectures to clarify misconceptions about Christianity. They utilize philosophical arguments, historical evidence, and scientific insights to support their claims, fostering a deeper understanding of the faith among both believers and skeptics.
