You must live your whole life according to the Christ you have received – Jesus the Lord; you must be rooted in him and built on him and held firm by the faith you have been taught, and full of thanksgiving. Make sure that no one traps you and deprives you of your freedom by some second-hand, empty, rational philosophy based on the principles of this world instead of on Christ. In his body lives the fullness of divinity, and in him you too find your own fulfilment, in the one who is the head of every Sovereignty and Power. In him you have been circumcised, with a circumcision not performed by human hand, but by the complete stripping of your body of flesh. This is circumcision according to Christ. You have been buried with him, when you were baptised; and by baptism, too, you have been raised up with him through your belief in the power of God who raised him from the dead. You were dead, because you were sinners and had not been circumcised: he has brought you to life with him, he has forgiven us all our sins.
