A stone that can be in the foundation, above ground level or at the summit of the roof (the “capstone”). The cornerstone of a large building gives it a reliable and firm foundation, leading to the cohesion and stability of the whole building. In Scripture, such foundation-stones are taken as symbolic of the basis of faith in Jesus Christ and the church. Jesus Christ is thus represented as both the foundation upon which the church is built, and the capstone which crowns the whole.
