Transubstantiation

What, exactly, is Transubstantiation?  If you break down the word it is not too difficult.  The first part, "trans" means "change" and the next part "substantiation" comes from the word "substance" and the "tion" part indicates it is an act or action.  Putting it all together, it means a "change of substance" or the process of changing a substance from one thing to another.  The change may not be in what you "see" - but in the "substance" which truly "is" what something "is."  

This is what happened when Jesus took bread, and blessing it He said, "This IS my body;" and with wine He declared, "This IS My blood."  Sure, it still looked like and tasted like bread and wine, but upon the declaration of God Almighty Himself, it became His body and blood!  Who are we to disagree or argue against the very Word of God?  He also didn't stop there!  He added, "Do THIS as often as you partake in THIS."  That command was given to the Apostles, the first bishops of the Catholic Church and they, in turn, pass on this authority to their successors and give faculties to local priests to "Do THIS" as well.  Any "church" which does not profess THIS is NOT the Church which Jesus Christ built.
