It really is an excellent book - not least because it explains so clearly why going regularly to Confession to confess venial sins is such a help in the spiritual life. As someone who has been discouraged in the past by the attitudes of some priests (and Bishops), it is great to hear the practice given a positive press.
"What we have in mind is the frequent and regular Confession of a person who in general does not commit mortal sin but rather lives a life of union with God and is bound to him by love. Such a person may, nevertheless, be guilty of many disloyalties and failings. He may have various weaknesses and bad habits and perverse inclinations, and he may have to struggle hard with his inordinate desires and his self-love. It is not a matter of indifference to him that here and there he has acted against his conscience, even though it be in nonessential matters."Do go and read Vox in Rama's review in full too.
