A great synod of elders from all the New England churches was assembled. All the way from Ipswich and Newbury on the east and from the Connecticut on the west the "teaching elders" made their way by water or by land, at public expense, that they might help the magistrates of Massachusetts to decide on what they should compel the churches to believe. For more than three weeks the synod at Cambridge wrestled with the most abstruse points of doctrine. The governor frequently had to interpose to keep the peace; sometimes he adjourned the assembly, to give time for heats to cool. A long list of errors, most of which were not held by anybody in particular, were condemned. A nearly unanimous conclusion on certain fine-spun doctrines was reached at length by means of affirmations couched in language vague or ambiguous. Cotton, who had been forced after debate to recant one opinion and modify others, assented to the inconclusive conclusions, but with characteristic non-committalism he qualified his assent and withheld his signature. XXI. [Sidenote: The persecution.] [Sidenote: Mass. Rec., i, 207.] The field was now cleared for the orderly persecution of the dissentients. Whelewright, Mrs. Hutchinson's brother-in-law, had been convicted of sedition in the preceding March on account of an imprudent sermon preached on a fast day. But his sentence had been deferred from court to court, apparently until after the synod. At the November court following the synod Whelewright was banished, and those who had signed a rather vigorous petition in his favor many long months before were arraigned and banished or otherwise punished. The banished included some of the most intelligent and conspicuous residents. Not until this November court had her opponents ventured to bring Mrs. Hutchinson to trial. Whelewright, standing by his hot-headed sermon, had just been sentenced; the abler but more timid Cotton had already been overborne and driven into a safe ambiguity by the tremendous pressure of the great synod. Vane had left the colony, and the time was ripe to finish the work of extirpation. The elders were summoned to be present and advise. XXII.
