It would be strange only if the chapter stopped at your quote :
Galatians 2: Lexham English Bible (LEB)
2 Then after fourteen years I went up again to Jerusalem with Barnabas, taking along Titus also. 2 Now I went up there because of a revelation and laid out to them the gospel that I preach among the Gentiles, but in private to the influential people, lest somehow I was running, or had run, in vain.3 But not even Titus who was with me, although he was a Greek, was compelled to be circumcised. 4 Now this was because of the false brothers secretly brought in, who slipped in to spy out our freedom that we have in Christ Jesus, in order that they might enslave us, 5 to whom not even for an hour did we yield in subjection, in order that the truth of the gospel might remain continually with you.
6 But from those who were influential (whatever they were, it makes no difference to me, God does not show partiality for those who were influential added nothing to me. 7 But these, when they saw that I had been entrusted with the gospel to the uncircumcision, just as Peter to the circumcision 8 (for the one who was at work through Peter for his apostleship to the circumcision was at work also through me for the Gentiles), 9 and when James and Cephas and John—those thought to be pillars—acknowledged the grace given to me, they gave to me and Barnabas the right hand of fellowship, in order that we should go to the Gentiles and they to the circumcision.
10 They asked only that we should remember the poor, the very thing I was also eager to do.
If you received a message from Jesus himself would you find it necessary to check out Jesus' message with other men?
I doubt it.....IMO Paul definitely expressed doubt in his Gospel.
Paul Lied and Sinned Against the Holy Spirit.
In Acts Chapter 15 the Leaders of the New Christian Church met to make some rules.
The following Scripture is their ruling.
Acts 15:28-29New American Standard Bible (NASB)
28 “For it seemed good to the Holy Spirit and to us to lay upon you no greater burden than these essentials: 29 that you abstain from things sacrificed to idols and from blood and from things strangled and from fornication; if you keep yourselves free from such things, you will do well. Farewell.”
Notice that the Holy Spirit complied with this ruling.
Also notice that one of the rulings by the Leaders and the Holy Spirit was to abstain from things sacrificed to idols.
BTW Paul was present at this meeting and surely was aware of this ruling.
But look what Paul preached.
1 Timothy 4:4-5New American Standard Bible (NASB)
4 For everything created by God is good, and nothing is to be rejected if it is received with gratitude; 5 for it is sanctified by means of the word of God and prayer.
1 Corinthians 8:4-10New American Standard Bible (NASB)
4 Therefore concerning the eating of things sacrificed to idols, we know that there is no such thing as an idol in the world, and that there is no God but one. 5 For even if there are so-called gods whether in heaven or on earth, as indeed there are many gods and many lords, 6 yet for us there is but one God, the Father, from whom are all things and we exist for Him; and one Lord, Jesus Christ, by whom are all things, and we exist through Him.
7 However not all men have this knowledge; but some, being accustomed to the idol until now, eat food as if it were sacrificed to an idol; and their conscience being weak is defiled. 8 But food will not commend us to God; we are neither the worse if we do not eat, nor the better if we do eat. 9 But take care that this liberty of yours does not somehow become a stumbling block to the weak. 10 For if someone sees you, who have knowledge, dining in an idol’s temple, will not his conscience, if he is weak, be strengthened to eat things sacrificed to idols?
After reading this passage by Paul in first Corinthians isn't it obvious that Paul is advocating eating food sacrificed to idols in contradiction of the command by the Holy Spirit and the Leaders of the Church?
Isn't this an intentional sin against the Holy Spirit?
