Ecclesiastical
A cornerstone (Greek: Άκρογωνιεîς, Latin: Primarii Lapidis) will sometimes be referred to as a "foundation-stone", and is symbolic of Christ, whom the Apostle Paul referred to as the "head of the corner" and is the "Chief Cornerstone of the Church" (Ephesians 2:20). Many of the more ancient churches will place relics of the saints, especially martyrs, in the foundation stone.
