The purpose of evangelization is to make Christ and the Church known to others so that they might receive the gift of faith and choose to convert to Christianity. It is a work accomplished in close collaboration with the Holy Spirit. The purpose of apologetics, on the other hand, is to clear away obstacles to faith by demonstrating that the claims about Christ, the Church and Catholic teaching are not contrary to reason. Broadly speaking, in other words, the focus of evangelization is on proclaiming the Gospel and the focus of apologetics is on arguing a position.
