....saith the Lord, and touch not the unclean thing;
2 Corinthians 6:17
"All Souls’ Day parades .....During the festivities, poor
citizens would 
beg for food and families would give them pastries called
“soul cakes” in return for their promise to pray for the family’s dead
relatives.
The distribution of soul cakes was encouraged by the
church as a way to replace the ancient practice of leaving food and wine
for roaming spirits." History.com
