Are you saying Jesus wasn't human? Carful now, this is a trap that you just set for yourself. Ain't faulty logic fun.
2) We (Lutherans, by the way) believe that the bread and wine are bread and wine, but that at the communion table those hosts are also the body and blood of Christ. The hosts don't lose their physical form, instead, they become invested with the actual presence of Christ.
IE you summon Christ down from heaven with your mighty powers invested in you to both defy scripture and blaspheme Christ by rendering him a liar through your accusatory action. Yes your actions do have ramifications. Christ said he sat down at the side of the Father and will not return till the end. You suggest you force him to return every time you do your encantations to turn bread and wine to blood and flesh. Now, either He's a liar because of your witness (blasphemy) or your philosophy is a lie. It can't be both ways.
Those who choose to observe the Lord's Supper in the manner prescribed by the Apostle Paul, may offend you personally, but they, none-the-less, base their practice upon Scripture.
