"But we preach Christ crucified, unto the Jews indeed a stumblingblock, and unto the Gentiles foolishness: But unto them that are called, both Jews and Greeks, Christ the power of God, and the wisdom of God." 1 Corinthians 1:23-24
"For as often as you shall eat this bread, and drink the chalice, you shall shew the death of the Lord, until He come." 1 Corinthians 11:26
I haven’t overlooked anything, FRiend. I never denied the crucifixion, I emphasized the fact that our hope isn’t in His death, but is in His resurrection. Maybe you missed that...
As for the RC claims, here is Paul, again...
*****************
1 Corinthians 3 (New International Version)
1Brothers, I could not address you as spiritual but as worldlymere infants in Christ. 2I gave you milk, not solid food, for you were not yet ready for it. Indeed, you are still not ready. 3You are still worldly. For since there is jealousy and quarreling among you, are you not worldly? Are you not acting like mere men? 4For when one says, “I follow Paul,” and another, “I follow Apollos,” are you not mere men?
5What, after all, is Apollos? And what is Paul? Only servants, through whom you came to believeas the Lord has assigned to each his task. 6I planted the seed, Apollos watered it, but God made it grow. 7So neither he who plants nor he who waters is anything, but only God, who makes things grow. 8The man who plants and the man who waters have one purpose, and each will be rewarded according to his own labor. 9For we are God’s fellow workers; you are God’s field, God’s building.
10By the grace God has given me, I laid a foundation as an expert builder, and someone else is building on it. But each one should be careful how he builds. 11For no one can lay any foundation other than the one already laid, which is Jesus Christ. 12If any man builds on this foundation using gold, silver, costly stones, wood, hay or straw, 13his work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each man’s work. 14If what he has built survives, he will receive his reward. 15If it is burned up, he will suffer loss; he himself will be saved, but only as one escaping through the flames.
16Don’t you know that you yourselves are God’s temple and that God’s Spirit lives in you? 17If anyone destroys God’s temple, God will destroy him; for God’s temple is sacred, and you are that temple.
18Do not deceive yourselves. If any one of you thinks he is wise by the standards of this age, he should become a “fool” so that he may become wise. 19For the wisdom of this world is foolishness in God’s sight. As it is written: “He catches the wise in their craftiness”[a]; 20and again, “The Lord knows that the thoughts of the wise are futile.”[b] 21So then, no more boasting about men! All things are yours, 22whether Paul or Apollos or Cephas[c] or the world or life or death or the present or the futureall are yours, 23and you are of Christ, and Christ is of God.
