From this page wilbe linked several important documents on the proper method of study. Saint Thomas Aquinas wrote a letter to someone who asked his advice on how to study. One of the things essential to proper study is having a strong spiritual life! Without a strong spiritual life, study has many dangers, as Saint John Eudes outlines. The holy Cure of Ars, Saint John Vianney states: We shall find out at the day of judgment that the greater number of Christians who are lost are damned because they do not know their own religion. So there is an order to study. We need to learn the basics of the Divine and Catholic Faith as contained in the Catechism. We recommend studying all of the articles posted in this section, as well as the Sanctification section in order to prepare to study as a Catholic. Also Catholics must be ready to make the Profession of Faith, for all study is based upon the Catholic Faith. If study does sometimes become an act of supernatural contemplation, it is inasmuch as by study we are led on to the love of God. Accordingly, it a person studies for the sake of acquiring knowledge, and not for the sake of edifying others and advancing in the love of God, it is well that he should realize that such study belongs to the natural contemplation (of philosophers), not to the supernatural contemplation (of theologians), Saint Thomas Aquinas.Saint Bernard: Some there are who desire knowledge merely for the sake of knowing, and this is shameful curiosity … and some there are who desire knowledge that they may put their knowledge up for sale for gain or for honors, and this is disgraceful trafficking: but some there are who desire knowledge that they may edify others, and this is charity: and finally, there are some who desire knowledge that they may thereby be edified themselves, and this is prudence.Study must be regulated by prudence. Fr. Irala in Achieving Peace of Heart says: 50%-12 hours for sleep, recreation, rest, etc. 50%-12 hours of study, work, productivity, etc. Priests who have only a handful of souls may become theologians and authors, and may serve the Church more lastingly by their writings than by their activity. Leisure and tranquility are two necessary conditions for sacred study. “The charm of leisure must not be indolent vacancy of mind, but the investigation or discovery of truth, that thus every man may make solid attainments without grudging others to do the same.” (Augustine City of God Book 19, Chapter 19) (The Eternal Priesthood, Henry Cardinal Manning, page 84)The spirit of silence must therefore pervade the whole of life. That is what matters more of all. It is said sometimes that solitude is the mother of results. Not solitude, but the state of solitude. So much so that we could, strictly speaking, conceive of an intellectual life based on two hours’ work per day. But does anyone imagine that having having set those two hours aside one may then act as if they did not exist? That would be grave misconception. Those two hours are given to concentration, but the consecration of the whole life is none the less necessary. (The Intellectual Life, Sertillanges, page 67) Normal workers estimate at from two to six hours the time that can be steadily used with fruitful results. (Page 97) Study must be moderate and must not take away from the duties of one's state of life. Here we recommend downloading useful information to your own computer from the interent and then printing it out on a laser printer. Laser printers can be obtained used, sometimes for as little as $5 in yard sales. In any case, these can then be assembled in notebooks and the various articles marked up, notes taken and questions asked to be answered on the next trip online.
