The answer here has to be “yes”. There’s no way to reconcile the two following passages, other than by allowing that circumstances had changed.
First, the Jerusalem council, dated to around 49 CE.
19 Therefore my judgment is that we should not trouble those of the Gentiles who turn to God, 20but should write to them to abstain from the things polluted by idols, and from sexual immorality, and from what has been strangled, and from blood. 21 For from ancient generations Moses has had in every city those who proclaim him, for he is read every Sabbath in the synagogues.” The Council’s Letter to Gentile Believers 22 Then it seemed good to the apostles and the elders, with the whole church, to choose men from among them and send them to Antioch with Paul and Barnabas. They sent Judas called Barsabbas, and Silas, leading men among the brothers, 23 with the following letter: “The brothers, both the apostles and the elders, to the brothers who are of the Gentiles in Antioch and Syria and Cilicia, greetings. 24 Since we have heard that some persons have gone out from us and troubled you with words, unsettling your minds, although we gave them no instructions, 25 it has seemed good to us, having come to one accord, to choose men and send them to you with our beloved Barnabas and Paul, 26men who have risked their lives for the name of our Lord Jesus Christ. 27 We have therefore sent Judas and Silas, who themselves will tell you the same things by word of mouth. 28For it has seemed good to the Holy Spirit and to us to lay on you no greater burden than these requirements: 29 that you abstain from what has been sacrificed to idols, and from blood, and from what has been strangled, and from sexual immorality. If you keep yourselves from these, you will do well. Farewell.” 30 So when they were sent off, they went down to Antioch, and having gathered the congregation together, they delivered the letter. 31 And when they had read it, they rejoiced because of its encouragement. 32 And Judas and Silas, who were themselves prophets, encouraged and strengthened the brothers with many words. 33 And after they had spent some time, they were sent off in peace by the brothers to those who had sent them. 35 But Paul and Barnabas remained in Antioch, teaching and preaching the word of the Lord, with many others also. (Acts 15:19-35)
So here it is clear that the Jerusalem council, including Paul, agreed to advise Gentile Christians not to eat the three types of meat most offensive to Jews.
And then, a few years later, 1 Corinthians, dated to around 57 CE:
23 “All things are lawful,” but not all things are helpful. “All things are lawful,” but not all things build up. 24 Let no one seek his own good, but the good of his neighbour. 25 Eat whatever is sold in the meat market without raising any question on the ground of conscience. 26 For “the earth is the Lord’s, and the fullness thereof.” 27 If one of the unbelievers invites you to dinner and you are disposed to go, eat whatever is set before you without raising any question on the ground of conscience. 28 But if someone says to you, “This has been offered in sacrifice,” then do not eat it, for the sake of the one who informed you, and for the sake of conscience— 29 I do not mean your conscience, but his. For why should my liberty be determined by someone else’s conscience? 30 If I partake with thankfulness, why am I denounced because of that for which I give thanks? 31 So, whether you eat or drink, or whatever you do, do all to the glory of God. 32 Give no offense to Jews or to Greeks or to the church of God, 33 just as I try to please everyone in everything I do, not seeking my own advantage, but that of many, that they may be saved. (1 Corinthians 10:23-32)
This is explicit, Paul says that it is okay to eat meat sacrificed to idols, the very worst kind of meat, as far as Jews were concerned.
Against this note that in 27 and 31 Paul in effect back-tracks to the same position as the Jerusalem council letter; If it will prevent people from coming to Christ, then better not to eat – consider the vulnerable people’s conscience not your own.
But even so, in making this allowance Paul does not change his position that one’s own conscience remains clear. As Paul says in Colossians 2: 16 “Therefore let no one judge you by what you eat or drink, or with regard to a feast, a New Moon, or a Sabbath.” And that statement is explicit that whatever one might not eat as a concession to the weakness of others, in no way is to one let oneself be judged or pressured into such rules.
