Neither. Give her the true Body and Blood of Jesus Christ under the species of wine, something which is in no way inferior to receiving him under the appearance of bread. It is giving her the true Sacrament which demonstrates the most love - not giving her normal bread. "Whosoever drinketh of this water shall thirst again: but he that shall drink of the water that I will give him shall not thirst for ever".
the Bible nowhere insists on wheat-based bread
The divine law of Christ requires wheat bread. "Unless the grain of wheat falling into the ground die, itself remaineth alone" (John 12:24) "the rest I will set in order, when I come" (1 Cor 11:34).
Um, I'm looking at the context of that passage right now, and it has absolutely nothing to do with the Eucharist at all. Care to try again?
