These principles once laid down and proved by the authority of Councils and Fathers, M. de Segur proceeds to give a plain and convincing reply to the difficulties urged by those who, having the dispositions required for frequent communion, are unwilling to permit it to themselves or to others. Of such difficulties he examines fifteen, which we here enumerate, in order that the eminently practical character of the book may be apparent to all: 1. To go frequently to communion, I ought to be better than I am; 2. I am not worthy to come so close to God; 3. Communion, when frequent, produces no effect; 4. I don't like to grow too familiar with holy things; 5. I am afraid to go to communion without first going to confession, and I cannot go to confession so often; 6. It is bad to go to communion without preparation, and I have no time to prepare myself as I ought; 7. I do not feel any fervour when I communicate; I am full of distraction and without devotion; 8. I do not dare to communicate often; I always relapse into the same faults; 9. I am afraid of surprising and scandalizing my acquaintances by going so often to Communion; 10. My family will be displeased if I become a frequent communicant; 11. I know many pious persons who communicate but seldom; 12. I am most anxious to communicate frequently, but my confessor will not allow me; 13. Frequent communion is not the custom in this country; 14. It is quite enough to go to communion on the great festivals, or at most once a month; 15. Your doctrine on frequent communion goes to extremes, and cannot be put in practice. These objections are solved in a manner at once convincing and pleasing. To the charm of a most agreeable style, and a great knowledge of the world of to-day, Mgr. de Segur unites the still higher excellence of sound learning and the spirit of the most tender piety. These qualities are especially remarkable in the sections which, at the end of his work, he devotes to prove how beneficial frequent communion is to children, to young persons, to Ecclesiastical students, and to the sick and afflicted. It will serve as a further recommendation of this little book to know that the Curé of Ars, who was an intimate friend of Mgr. de Segur, acted according to its maxims in the discharge of his ministry, and with what abundance of good to souls, France and the world well know.
