Though the great power of the church, in ancient times, weakened the authority of the crown, and interrupted the course of the laws, it may be doubted, whether, in ages of such violence and outrage, it was not rather advantageous that some limits were set to the power of the sword, both in the hands of the prince and nobles, and that men were taught to pay regard to some principles and privileges. The chief misfortune was, that the prelates on some occasions acted entirely as barons, employed military power against their sovereign or their neighbours, and thereby often increased those disorders which it was their duty to repress. The Bishop of Salisbury, in imitation of the nobility, had built two strong castles, one at Sherborne, another at Devizes, and had laid the foundations of a third at Malmesbury: his nephew, Alexander, Bishop of Lincoln, had erected a fortress at Newark: and Stephen, who was now sensible from experience of the mischiefs attending these multiplied citadels, resolved to begin with destroying those of the clergy, who, by their function, seemed less entitled than the barons to such military securities [s]. [MN 1139.] Making pretence of a fray which had arisen in court between the retinue of the Bishop of Salisbury and that of the Earl of Britany, he seized both that prelate and the Bishop of Lincoln, threw them into prison, and obliged them by menaces to deliver up those places of strength which they had lately erected [t].
