“The unity of the faithful in Christ’s Body is not organizational, although an organization is necessary, and although those who admire the Church for its unity of belief and faith and liturgy attribute this to its organization.  The Church is, rather, an organism.  As a human body is one because it has one soul – the Holy Spirit of God – one visible Head – Peter and his successors and one invisible Head – Christ.  As Christ took upon Himself a human nature from the womb of His Mother (overshadowed by the Holy Spirit), so He took from the womb of humanity (overshadowed by the Pentecostal Spirit) His Mystical Body, the Church.” Archbishop Fulton Sheen
