Taking Protestant communion unworthily is to act “unworthily towards the body and blood of the Lord” because they too “recognize the Body” of Jesus as God’s body, through bread and grape juice
No doubt. But, Protestant communion is an act of disobedience towards God.
1st. God did not establish any Protestant denomination. God, in the Person of Jesus Christ, established Catholicism.
2nd. God did not authorize Protestants to confect the Eucharist. God authorized the Catholic Church to confect the Eucharist.
3rd. Protestants don’t regard it a sin to miss their gatherings. God regards it a sin of the highest order to miss the Mass.
3a. Why? Because it is in the Mass that the Eucharistic Sacrifice is offered. The one remaining sacrifice for the forgiveness of sins. And those who neglect this gift of God, insult Him to the highest degree and make themselves His enemies:
Hebrews 10:25 Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
26 For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
27 But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
28 He that despised Moses’ law died without mercy under two or three witnesses:
29 Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?
30 For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people.
31 It is a fearful thing to fall into the hands of the living God.
