Should it be desirable to use the church building and any other buildings or property of any Protestant Episcopal church heretofore or hereafter organized and existing in this state, as and for a cathedral, it shall be lawful for such church, at its first meeting, or at any annual meeting, or at a special meeting duly called for that purpose, to adopt a plan not inconsistent with this act, nor with the constitutions and canons, doctrine, discipline and worship of the Protestant Episcopal church, by which it may adapt itself and its property to such use; which plan may provide for a dean or other officer, who shall be elected with the advice and consent of the bishop of the diocese in which such church may be located, in accordance with the canons of said diocese, and who shall be ex-officio rector.
