Hi,
It doesn’t sound so much that you don’t believe in transubstantiation as that you don’t fully understand what it is. Basically, it simply affirms that the bread and the wine truly become the body and blood of Jesus—as He said that they do. Even though they still look, feel and taste like bread and wine, they are really his body and blood. If you believe this, you may certainly receive Holy Communion. Feel free to write me privately about this by clicking on my name above.
