This is a second for “Catholicism for Dummies” by Rev. John Trigilio and Rev. Kenneth Brighenti. It is solid information, and plainly written, even entertaining at times. As a religious educator and cradle Catholic, I turn to this to help explain the faith to non-Catholics.
While I treasure and use the Catechism of the Catholic Church often, it can be overwhelming to someone who has little prior knowledge of the faith.
God bless and keep you as you embark on this journey home. You are part of a large and supportive family, both in heaven and on earth. Our hearts are restless, God, until they rest in you (St. Augustine)
