The former while they want to be called “church” aren’t “church”. God Himself in the flesh established His Church on Pentecost. That is the One true Church. No other. It is still here today, 2000 years later, with pope Francis 266th successor to St Peter at the helm.
Protestants, no matter the stripe, can do the following when they meet, because they have no valid priesthood.
This is speaking of the true Church Jesus established Himself
23 Let us hold fast the confession of our hope without wavering, for he who promised is faithful; 24 and let us consider how to stir up one another to love and good works, 25not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near. 26 For if we sin deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, 27* but a fearful prospect of judgment, and a fury of fire which will consume the adversaries. 28* A man who has violated the law of Moses dies without mercy at the testimony of two or three witnesses. 29* How much worse punishment do you think will be deserved by the man who has spurned the Son of God, and profaned the blood of the covenant by which he was sanctified, and outraged the Spirit of grace?
one will notice
By deliberately failing to meet on Sunday (the Day) as is the habit of some
*]it is already considered a mortal sin for that person because
*]there is no sacrifice for sins for THEM as a result of deliberately failing to meet on Sunday.
*]They profane the blood of the covenant for failing to meet
*]They spurn the son of God and outrages the spirit of grace for not meeting
*]as a result, punishment for that person and a fearful prospect of judgement and a fury of fire awaits because that person is considered an adversary of God for deliberately not meeting for the Eucharist (not my words but from scripture)
And WHY is all THAT describing the Eucharist (mass)?
*]what is the sacrifice for sin and blood of the covenant talking about when they meet? It’s the Eucharist. The summit of our faith. Matthew 26:26-28. Jesus said it’s the Eucharist, the consecrated bread is His body, and the consecrated wine is my blood of the covenant, 1 Corinthians 11:25 ] which is poured out for many for the forgiveness of sins. Jesus the son of God said those words instituting the Eucharist. Jesus further describes the importance of the Eucharist for the soul. Jn 6:53 unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. Life of the soul is **grace. **THAT’s the Eucharist.
Therefore, the one who deliberately blows off (mass) the Eucharist on Sunday, after being given this knowledge of truth,
*]no sacrifice for sin is left for THEM
*]they profane the blood of the covenant
*]they spurn the son of God & outrage the spirit of grace
*]and judgment awaits them
That’s how important the Eucharist is, ergo the mass, and it is to be celebrated when we meet . It describes also in [FONT="]descriptive detail, why it’s a mortal sin to deliberately miss on “the Day”. It also shows why it is a day of obligation to go to mass[/FONT]
