 The altar, a symbol of Christ at the heart of the assembly, so deserves special reverence, which we'll see with a bow or a kiss. Yeah, so the presider, and usually often you see the bishops kissing the altar, right? The altar is consecrated, right? It's the only piece of furniture in a church that's consecrated. There's an enormous ritual behind it. There's oil poured over it, and then mass can be celebrated. And you see, and there's usually relics in an altar of martyrs as well.
