The Grounds of Catholic Doctrine: An Apologetic Call to Communion

Saint Peter urged Christians to: "Always be ready to make your defense to anyone who demands from you an accounting for the hope that is in you; yet do it with gentleness and reverence." (1 Peter 3:15-16)

Yet, some Christians mistakenly assume that the gospel message -- Catholic doctrine -- is mysterious, difficult to understand, and impossible to explain. They do not realize that the "good news" of Jesus Christ is easy to understand, reasonable, and winsome.

Pope Pius IV wrote The Grounds of Catholic Doctrine: An Apologetic Call to Communion in an easy-to-read, question-and-answer format to encourage, strengthen, and equip the faithful. This work also invites those who are yet outside the Church to join Catholic believers on the journey of a lifetime in unity, peace, and truth.

"No eye has seen, nor ear heard, nor the human heart conceived, what God has prepared for those who love him." (1 Cor 2:9)
