When William the Conqueror defeated the English King Harold at the Battle of Hastings, he felt some remorse for the many who died there. So he built an Abbey to atone for all the blood shed. He built it on the battlefield itself. He built it so that the high altar would be on the very spot where King Harold died.

But we can never atone for our sins by building churches, nor by giving money, nor by good deeds. "What can wash away my sin? Nothing but the blood of Jesus." And the communion table, wherever it sits, is a memorial to His death for us at Calvary.
