Save as is in this Act expressly provided as to ministers of the Church of England, nothing herein contained shall authorise or enable any such minister who shall not have become a declared member of any other Church or denomination, or have executed a deed of relinquishment under the Clerical Disabilities Act, 1870, to do any act which he would not by law have been authorised or enabled to do if this Act had not passed, or to exempt him from any censure or penalty in respect thereof.
