So what? The Catholic church didn't serve the cup. Jesus did. And that's what He commanded that we do.
Who gave the Church authority to deny the fullness of communion to anyone?
Jesus did when He said:
"Truly I say to you, whatever you bind on earth shall have been bound in heaven; and whatever you loose on earth shall have been loosed in heaven." Matthew 18:18
You really have to stop projecting YOPIS onto Catholic doctrines. Just because the "Lord's Supper" is a symbolic presentation of Wonder Bread and Welches Grape Juice in your church does not negate the Epiclesis and the Real Presence in the Eucharist in the Catholic Church. That trade off is one you freely made when you chose yourself as the final arbitrator of Truth and what is and isn't the meaning of Revealed Word.You are not the first to fall victim to that. Satan tempted others, including Our Lord, to worship contrary to Scripture.
Both species of the Eucharist are present in every Catholic Mass since the first century and Christ has been wholly present in which ever species the laity receive. If that is good enough for those of us who choose to receive Him, why should we care what any nonbeliever thinks. We don't do it for you.
You have no authority to interrogate me and question the Church. I owe you no answers, only kindness, the Truth, my forgiveness and my prayers. As I have so often said I am only going to correct the erroneous and errant versions of the teaching of the Church posed by the ignorant and the anti-Catholic heretics and apostates. I am not going to engage in any debates.
May the Blessings of Christ and the Peace and Joy of the Holy Spirit be with you.
