'''Orthodox Christianity''' is the life in faith of the [[Orthodox Church]], inseparable from that concrete, historic community and encompassing its entire way of life. The Orthodox Christian faith is that faith "handed once to the saints" ([[Book of Jude|Jude]] 3), passed on in [[Holy Tradition]] to the [[apostles]] by [[Jesus Christ]], and then handed down from one generation to the next, without addition or subtraction.  The sole purpose of Orthodox Christianity is the salvation of every human person, uniting him to Christ in the Church, transforming him in holiness, and imparting eternal life. This is the Gospel, the good news, that Jesus is the Messiah, that he rose from the dead, and that we may be saved as a result.
