Philosophical consideration of Eucharistic Consecration

[yablabo]

Thank you for your response.

I am not denying that the altar breads and wine are upon the altar.  I am proposing that these are neither "before the priest" nor "upon a corporal" in my specific case.  If these had only to be "on the altar", then why did Fr. McNamara include "before the priest" and "upon a corporal" in the statement he made?

Also, if intention makes the sacrament, as you imply, then does the priest's intention to consecrate a cake or a cup of grape soda suffice to confect the sacrament? 

My whole point in this examination is regarding the matter of the sacrament, not the intention of the priest.
