This holy work commences with a summary of Christian Doctrine on what every Catholic must believe in order to be Catholic. This is followed by what every Christian must do in order to be Catholic. Then we proceed to the morning exercise, including an instruction on meditation. "Meditation, consisting of considerations on the great truths of Christianity, pious affections, frequent elevations of the soul to God, and serious resolutions of amendment, is certainly one of the most important exercises of a christian life, and ought daily to be performed by all those, who would devote themselves, in earnest, to the service of God. The morning is the most proper time for the performance of this duty. ... " Specific useful subjects of meditation will be found later on in this work. This is followed by evening exercises. This work contains devotions for Mass, Confession and many other useful devotions for a sincere Christian.
