Peter Pett's Commentary on the Bible
Galatians 2:4
‘And that because of false brothers surreptitiously introduced, who came in surreptitiously to spy out our liberty which we have in Christ Jesus, that they may bring us into bondage.'
The pressure on Titus resulted not from the doubts of the leadership but from the sudden and unexpected introduction into the situation of leading Judaisers who had not been expected and were not strictly invited, but who had clearly been hurriedly called in by some who had learned of the proposed discussions. These Judaisers presumably demanded that Titus be circumcised. They wanted him to become a recognised proselyte. Thus circumcision had now become a crunch point. The question that was at stake was whether every Gentile Christian needed to be circumcised, or whether they could be true Christians without being circumcised.
However, that does also raise the question as to why the Judaisers wanted them to be circumcised, and why it was seen as so important. And there could only be one answer to that, and that is that it was because they saw the church and Israel as being equivalents. They considered that in order to become true Christians all who believed had to become Jewish proselytes. It is therefore significant that Paul never argues that there was no intention of such people becoming members of Israel. For he also recognises that to become a Christian is to become a part of Israel. His argument is rather that circumcision is unnecessary because in Christ all that is necessary for salvation can be found. And this includes whatever circumcision signifies. For all who believe in Jesus Christ have already been circumcised with the circumcision of Christ (Colossians 2:11). Thus circumcision is no more required than the continual offering of sacrifices. They can be members of the covenant of Israel without it. In his eyes therefore the church is the new Israel but does not require circumcision for entry into it, because it is united with Christ, and therefore with His circumcision.
‘False brothers.' They were false because they were seeking to use pressure to enforce something contrary to the Gospel of free grace as Paul knew it. He saw clearly the issues involved. By demanding circumcision as necessary for salvation they were making salvation depend on some form of ritual. But Paul's reply is that salvation is by faith alone. No form of ritual can therefore be demanded in order for a person to be saved. Salvation is by faith alone (Galatians 2:16). (We must recognise here that some of his opponents may well later have accepted that they had been wrong, for they were all at this stage still seeking to lay down the foundations of belief, and the questions to be sorted out were not simple ones. Compare the problems that Peter had in Acts 10-11).
‘To spy out.' Together with ‘surreptitiously' this sums up their behaviour. They were coming with improper motives among those who were gathered there, in order to sow doubt and dissension and in order to try to bring division.
‘Our liberty that we have in Christ Jesus, that they may bring us into bondage.' This was the question at issue, whether trusting in Jesus Christ, the crucified and risen Lord, had freed them from the necessity to compulsorily observe the legalistic ceremonies and requirements, together with the ethical requirements, laid down by leading Jewish teachers. The question was not whether Jews should be circumcised, even Christian Jews, but whether it was absolutely necessary for Gentiles. In other words, was following Jewish ritual requirements an essential for salvation?
Paul, who had been delivered from the burden of such requirements when he put his trust in Christ, recognised at once that once circumcision was accepted as necessary, it would bring the person involved under the whole Jewish legal system. By being circumcised they would be acknowledging that they must keep the whole Law of Moses, and all the emphasis was being placed on the ritual ones. And he firmly believed that the demand for such a fulfilment of Jewish ordinances on those not brought up to it would be a burden too heavy to bear for those to whom they were totally foreign, and that they were not a necessary part of the Gospel. He recognised that they simply brought men into unnecessary bondage. It was fine for Christian Jews, if they wished, to continue with these practises, as long as they did not make them necessary for salvation. But as an essential for salvation they must not be required of anyone.
Some churches would later invent further burdens to lay on Christians, in the form of other ceremonies and requirements, and declare them essential for salvation, and even today we have particular forms of baptisms and particular approaches to the Sabbath which are stressed by some as being such. These too come under Paul's condemnation where they are claimed to be essential to salvation. For his argument is that the only requirement for salvation is the free response by faith through His Spirit to God's gracious offer of salvation through Christ, resulting from the preaching of the cross (compare 1 Corinthians 1:17). He is saying that while ceremonies may be helpful, and may have their place, they must remain in that place. They must never be seen as necessary for salvation.
In fact we know from Acts that the Apostles were quite firm in their support of Paul's position. Peter stated, “We believe that we shall be saved through the grace of the Lord Jesus in the same way as they,' and at the Assembly in Jerusalem rejected the need to burden the Christians who were not Jews with Jewish ceremonial and ritual requirements (Acts 15:7). James, the Lord's brother, concurred. Minimal conditions were then laid down at that meeting concerning what would be required of Gentile Christians, and it was agreed that all Christians should refrain from ‘the pollutions of idols (eating things sacrificed to idols - Acts 15:29), and from fornications, and from things strangled and from blood' (Acts 15:20). The former were necessary as being directly against God and as giving a false witness to outsiders, the latter necessary if they were to eat and consort with Christian Jews. For there could be no fellowship over meals without it, and in those days meal fellowship was central.
