According to research done at Leicester University by Miriam Gill, the Hardwick wall-painting represents in its lower part the Seven Deadly Sins:
Pride
Envy
Anger
Avarice
Sloth
Gluttony
Lust
and in its upper part the Seven Corporal Works of Mercy:
Feed the hungry
Give drink to the thirsty
Welcome the stranger
Clothe the naked
Visit the sick
Visit the prisoner
Bury the dead
though only five of the latter are known to be present.
Apparently wall paintings with this theme were not uncommon in English churches in medieval times, though most have been destroyed or obliterated. Hardwick was one of just twenty churches used in the Leicester University study, the others being: Arundel, Brooke, Catfield, Dalham, Hoxne, Hunworth, Ingatestone, Kentford, Kingston, Milcomb, Milton Abbas, Netherbury, Oddington, Quatt, Ruabon, Ruislip, Stanningfield and Trotton. Hardwick is unusual in that the Sins are portrayed riding on animals, the only other place where this is found being Langar in North Wales.

It is probable that the wall painting was whitewashed over not because of fear or rejection of superstition, as surmised by John Willis Clark in his 1859 article, but because in certain eyes it appeared to justify Redemption by Good Works rather than by Faith alone.
