Fr. Giesler' s Junia trilogy vividly recounted the lives of the early Christians and their struggle to be faithful to their newfound faith in Jesus Christ. In Family Grace, Fr. Giesler tells a similar story, but within the context of a contemporary American family that discovers the Catholic Faith in gradual and unexpected ways. He vividly narrates their temptations, failures, and victories in a setting very similar to what the early Christians faced: a society often hostile to the truth and goodness of the Gospel. As he did in his previous novels, Giesler uses the message of St. Josemarí a Escrivá as his inspiration—-with his call to become saints and apostles in the middle of the world, a calling very similar to that of the early followers of Christ.
