What does it mean that Christ is the head of the corner?

The term 'head of the corner' reflects not only Christ's primacy in salvation but also His authority over the Church. As outlined in 1 Peter 2, for believers, Jesus is precious and serves as the foundation from which spiritual growth occurs. Those who believe are built into a spiritual house, emphasizing that Christ initiates and completes our salvation. Conversely, those who reject Him stumble at this cornerstone, illustrating the division between believers and disobedient builders who trust in their efforts. The head of the corner indicates that all spiritual growth is centered on Christ, and it is through Him that the Church flourishes.
