I remember some years ago sitting near the back of a big congregation comprised mainly of young people in a very 'with-it' church that sang all the latest chorusses (actually that should be spelled chorus'). They had a great rock band of their own musicians that played at their youth-orientated services. The visiting preacher that night had been a youth leader at that church some fifteen years or more before.
He chose to bring the topic of circumcision into his preaching, and deliberately treated the matter very lightly, carefully phrasing his remarks to extract as many schoolboy sniggers from as many of those in the audience as possible. I deliberately chose 'audience', feeling it was a better word to use than 'congregation', because of the tone of the meeting.
So why does circumcision feature in the Bible, why should it ever be mentioned from Christian pulpits - and in what context - and why did the Jews practice it?
The first Biblical mention of circumcision comes in Genesis when God had declared to Abram, now Abraham, that resultant upon his (Abraham's) great faith, He (God) was going to create a nation from Abraham's progeny. This was to be despite Abraham's and his wife's great ages, and the fact that the only child Abraham had was not of Sarah, but of Hagar, Sarah's servant.
It is also very interesting to note that in the following scripture it shows that Abraham, his servants, and the progenitor of the Arab race (Ishmael) were all circumcised, well ahead of the conception, birth and circumcision of the Jewish race, the progenitor of which was Isaac. It was also a long time before Moses came on the scene.
Now all the people that came out were circumcised: but all the people that were born in the wilderness by the way as they came forth out of Egypt, them they had not circumcised. For the children of Israel walked forty years in the wilderness, till all the people that were men of war, which came out of Egypt, were consumed, because they obeyed not the voice of the LORD: unto whom the LORD sware that he would not shew them the land, which the LORD sware unto their fathers that he would give us, a land that floweth with milk and honey.
And their children, whom he raised up in their stead, them Joshua circumcised: for they were uncircumcised, because they had not circumcised them by the way. And it came to pass, when they had done circumcising all the people, that they abode in their places in the camp, till they were whole. Joshua 5:2-8
Hold on, I hear you saying. Does that mean that Christians, like Jews and Muslims, should be circumcised?
Certainly Not.
That is made very clear by all of the Apostles when Gentiles started being admitted to the church. While the quotes below are from Paul's writings, the other Apostles were of similar mind as we can read.
But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses. Acts 15:5
Forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, Ye must be circumcised, and keep the law: to whom we gave no such commandment: Acts 15:24
Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised. 1Corinthians 7:18
But neither Titus, who was with me, being a Greek, was compelled to be circumcised Galatians 2:3
Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing. For I testify again to every man that is circumcised, that he is a debtor to do the whole law. Galatians 5:2,3
For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh. Galatians 6:13
In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ. Colossians 2:11
And the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live. Deuteronomy 30:6
But every man's servant that is bought for money, when thou hast circumcised him, then shall he eat thereof. Exodus 12:44
And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof. Exodus 12:48
Christians are supposed to believe that they have been 'bought for a price', and that they are in reality also the slaves or servants of Christ. So once a Christian has become 'circumcised of the heart', then he or she can be regarded as fit to eat and fellowship with the other Saints.
So when a stranger comes and wants to 'sojourn', that is to say become one of the 'extended Christian family', because they wish to partake of the replacement to the Passover, the communion of the body and blood, then they too need to be circumcised according to the era in which they now live, the Christian era, and be circumcised in the heart.
That points towards the need for someone being brought to Christ having it explained to them that there is more to it than just sitting in a position where he or she can say 'Okay, so I am saved, now just let me go about my daily business the way I did before, or with a barely perceptible superficial change'.
There is also the point that the action of the knife in cutting away the superflous physical flap causes physical pain to the individual, just as the deliberate elimination of worldly, secular fallen attitudes and thoughts causes us spiritual pain while we are doing it. There is no pain if we can't be bothered to circumcise our hearts. However, neither is there any fellowship nor any 'belonging' either. We are living a sham, just as the uncircumcised Israelites were, if we have that attitude.
The bible teaches strongly that the 'Nation Israel' in the Old Testament was not to have any social intercourse at all with unbelievers, and a careful reading of the New Testament says exactly the same to God's later 'chosen people', in regard to those who flatly refuse to listen, follow and obey the message of the Lord Jesus. Where does that place you?
Some Christians will dispute that last remark. It is my personal opinion, based upon careful reading of what the scriptures actually say. God is unchangeable. He does not change His mind, never had to create a 'Plan B' - even for 'the Garden of Eden' situation - and He has always required obedience of those who often quite presumptuously claimed to be His chosen.
So there we have my exigesis on circumcision. Not a smutty story that can be giggled at behind the back of your hand, nor smirked and guffawed at when you are blind drunk and unable to think straight, let alone control your tongue.
Why did I write that last paragraph? Because that is the scenario in which I have heard the topic ridiculed, a scenario in which I have sat, stone cold sober and with my wits about me, because of having being invited to meet with the people concerned.
