A few things:
Arthur was buried with a LEADED CROSS UNDERNEATH HIM. I don't have the words to explain the importance of this concisely, so I won't attempt. I will quickly explain that LEAD > GOLD is important to understand. Why it was buried UNDER him was important to understand (the custom is a cross on top of the chest).

Wear the grudge like a crown of negativity
Calculate what we will or will not tolerate
Desperate to control all and everything
Unable to forgive your scarlet lettermen
Clutch it like a cornerstone, otherwise it all comes down
