This highly readable introduction to the roots of many Catholic beliefs and practices provides a sense of connection to our brothers and sisters who have gone before us and who helped shape the faith. Mike Aquilina makes it clear that as far as the essentials are concerned, a time-travel trip back to the beginning of the Church would reveal a Church familiar to Catholics today. Just as an acorn grows into a tree and yet remains the same plant, so the Catholic Church is a living organism that has grown from the faith of the earliest Christians into the Body of Christ we know today.
