If you are making the one time sacrifice for sins present "again" in the Eucharist to be received "again", you are redoing the cross.
Had you received that one time sacrifice for sins the first time or not?
Then when you repeat that again, you are redoing the cross as if that one time sacrifice for sins was not good enough the first time you had received it because you are receiving it again.
The Holy Ghost is in you so you do not need to receive it again.
Those that wish to have their sins forgiven can just go to Jesus for that.
1 John 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
By walking in the light as He did in fellowship with the Father & the Son, is how His blood cleanses us from sins too.
1 John 1:3 That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. 4 And these things write we unto you, that your joy may be full.......7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
The Eucharist does not do that. Jesus Christ is already in you which is why forgiveness is that accessible so that is why the Mass is not necessary because it was never a means to obtain forgiveness or the remission of sins by.
Acts 10:43 To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.
So believe Him, brother. You don't need the Eucharist nor be a slave to the RCC' system of works to get your sanctfication from when all invitations points to Jesus for life.
2 Thessalonians 2:13 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth:
How was this done... ?
2 Thessalonians 2:14 Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ.
You are not going to find such an emphasis for salvation in any of the N.T. instructions to the churches that you find so many of in the Catholic catechism. Truly, the simplicity of the gospel is lost in the catechism.
How many times Does Jesus repeat the sacrifice at the cross when he did communion himself?
Luke
19And when He had taken some bread and given thanks, He broke it and gave it to them, saying, “This is My body which is given for you; do this in remembrance of Me.” 20And in the same way He took the cup after they had eaten, saying, “This cup which is poured out for you is the new covenant in My blood.
You would argue here with Jesus Christ. You would tell him, That's not the blood poured out for the new covenant...... Its tomorrow.
1 Corinthians 11
23For I received from the Lord that which I also delivered to you, that the Lord Jesus in the night in which He was betrayed took bread; 24and when He had given thanks, He broke it and said, “This is My body, which is for you; do this in remembrance of Me.” 25In the same way He took the cup also after supper, saying, “This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.”
Look Paul says "This cup is the new covenant in my blood" How many times is Paul redoing the sacrifice?
Paul is delivering something here, what is it? These people are already saved.
