The rules of some of these religious guilds may be found in Stow's "Survey of London," _e.g._, of St. Barbara's guild in the church of St. Katherine, next the Tower of London (in book ii. p. 7 of Hughes's edition.) We find bequests to the guild priests, in common with other chaplains, in the ancient wills, _e.g._, in 1541, Henry Waller, of Richmond, leaves "to every gyld prest of thys town, vi{d}. y{t} ar at my beryall."[237] Dr. Rock says,[238] "Besides this, every guild priest had to go on Sundays and holy days, and help the priests in the parochial services of the church in which his guild kept their altar. All chantry priests were bidden by our old English canons to do the same." The brotherhood priest of the guild of the Holy Trinity, at St. Botolph's, in London, was required to be "meke and obedient unto the qu'er in alle divine servyces duryng hys time, as custome is in the citye amonge alle other p'sts." Sometimes a chantry priest was specially required by his foundation deed to help in the cure of souls in the parish, as in the case of a chantry founded in St. Mary's, Maldon, and Little Bentley, Essex;[239] sometimes the chantry chapel was built in a hamlet at a distance from the parish church, and was intended to serve as a chapel of ease, and the priest as an assistant curate, as at Foulness Island and Billericay, both in Essex. But it is very doubtful whether the chantry priests generally considered themselves bound to take any share in the parochial work of the parish.[240] In the absence of any cure of souls, the office of chantry or guild priest was easy, and often lucrative; and we find it a common subject of complaint, from the fourteenth to the sixteenth centuries, that it was preferred to a cure of souls; and that even parochial incumbents were apt to leave their parishes in the hands of a parochial chaplain, and seek for themselves a chantry or guild, or one of the temporary engagements to celebrate annals, of which there were so many provided by the wills of which we shall shortly have to speak. Thus Chaucer reckons, among the virtues of his poore parson, that-- "He set not his benefice to hire, And let his shepe accomber in the mire, And runne to London to Saint Poule's, To seken him a chauntrie for soules, Or with a brotherhood to be with-held, But dwelt at home, and kepte well his fold." So also Piers Ploughman-- "Parsons and parisshe preistes, pleyned hem to the bisshope, That hire parishes weren povere sith the pestilence tyme, To have a licence and leve at London to dwelle And syngen ther for symonie, for silver is swete."
