You have actually seen communicants smear the blood of Christ on their sensory organs as described by Saint Cyril and hold to a 12 hour fast? To me it seems that communion in the hand was chosen and later justified by cherry picking one single quotation out of context. 

St.Leo was a contemporary of St. Cyril how was his promotion of communion on the tongue and forbidding laity to touch the host a historical aberration.

Or what about Saint Eutichiano who also forbade the laity of ever touching the host? He pre-dated Saint Cyril by 100 years.

Is it not more reasonable to conclude that the rites of Rome and Jerusalem were different, and that the 5 chapters of the mystagogal catechesis was meant for a different audience than the 18 other lectures, some scholars believe it was meant for the newly ordained?
