Sách nói: Baltimore Catechism, No. 2 -- Catechism of Christian Doctrine

A catechism is a summary of the principles of Christian religion and articles of the faith. The Baltimore Catechism specifically was the de facto standard Catholic school text in the United States from 1885 to the late 1960s. It was the first such catechism written for Catholics in North America, replacing a translation of Bellarmine's Small Catechism. The Baltimore Catechism remained in use in nearly all Catholic schools until many moved away from catechism-based education, though it is still used up to this day in some. (Summary by Wikipedia)
