That the Holy Communion is not Lightly to be Forborne

You ought often to have recourse to the fountain of grace and of divine mercy, to the fountain of goodness and all purity; that you may be healed of your passions and vices, and may deserve to be made stronger and more vigilant against all the temptations and deceits of the devil....How happy is he, and how acceptable to God, who so lives and keeps his conscience in such purity, as to be prepared and well disposed to communicate every day, were it permitted to him, and he might pass without observation!...And when, indeed, he is lawfully hindered, he should yet always have a good will and a pious intention of communicating, and so he will not be without the fruit of the Sacrament.  For every devout person may every day and every hour, without any prohibition, approach to a spiritual communion with Christ with much profit.
