Under the leadership of James the Lord's brother the Christian Church at Jerusalem was probably the most influential of all existing Christian communities. It could boast a system of internal organisation under authoritative resident leaders; it was an important missionary centre, despatching apostles and recalling them, or sending advisors to them when they were in difficulties. Neither the prestige nor the destiny of the Jerusalem Church were the immediate concern of the author of the Acts of the Apostles, and it is Hegesippus who keeps us informed of its progress. The stability of that Church was apparently shattered shortly after the death of James, when the Jews revolted against the Romans and ‘immediately Vespasian attacked them’. We hear no more about the Jerusalem Church directly from Hegesippus until he tells of a meeting convened to elect a successor to James, and Eusebius tells us that this meeting took place after Jerusalem had been taken in A.D. 70.
