Seems that the concern about spilling the cup is unwarranted.
Jesus bled out all over the ground when He died. If some wine gets spilled, the biggest problem would be stains on the carpet or a puddle on the floor. Easily remedied.
In the new version it’s the flesh that counts not all that bleeding.
Every drop of the Consecrated cup and every piece of the consecrated bread contains the Full Resurrected Christ in tact- Body ,Blood, Soul and Divinity.
Perhaps you should realize that Jesus was Resurrected and Ascended-He did so intact. There is no Blood left on earth that was shed from the crucifixion.
