In a nutshell, Protestant theology has Jesus being incarnated for the purpose of saving us from sin, so that we may live our lives in Heaven. Catholic theology teaches that our divine union with Christ was intended from eternity (CCC 398), and we were to reunite with Jesus Christ and live Heaven (who is the person of Christ) on earth. Sin modified the details of this plan, but not the core plan. There is a strong element of agency in Protestant theology, (angles and even humans are agents, but not the person of Christ). There is a strong element of personality in Catholicism, (angels and humans actually become the person of Christ, who is now the entire body of Christ). See the following topics in this book for details of these ideas.
