Canon LIX
Baptism is by no means to be administered in an oratory which is within a house; but they who are about to be held worthy of the spotless illumination are to go to a Catholic Church and there to enjoy this gift. But if any one shall be convicted of not observing what we have determined, if he be a cleric let him be deposed, if a layman let him be cut off.
In oratories built in houses they shall not celebrate baptism. Whoever shall not observe this, if a cleric he shall be deposed, if a layman he shall be cut off.
