A four-part theological apologetic that defends core Christian doctrines through philosophical argument and scriptural exposition. The first section presents proofs for God’s existence, attributes, providence, and the soul’s immortality. The second argues that Christian faith coheres with truth and reason. The third examines central mysteries, asserting they are not intrinsically impossible nor contrary to rational thought. The fourth affirms the truth of Christian teaching while rebutting the claims and errors of rival philosophers, pagan practices, followers of other religions, and assorted heretical positions, combining intellectual argumentation with pastoral intent to instruct and vindicate the faith.
