The Sagrada Familia is a symbolic expression in stone of the Christian faith. In this temple, an exaltation of the Family of Nazareth as a model for a united family, Christians, especially Roman Catholics, can recognise the tenets of their faith. Likewise, those who profess a different faith or none at all can find in it the keys for understanding the Christian religion: the history of the Church, the Sacred Scriptures, the tradition of dedication to the Saints, Christian doctrine and worship.
