be useful.

The chief aim of the book is to be practical, and to teach Catholics
what they should know, and how these truths of their Catechism are
constantly coming up in the performance of their everyday duties. It is
therefore neither a book of devotion nor of controversy, though it
covers the ground of both. As in this book the explanations are
interrupted by the questions and answers of the Catechism proper, it
will, it is hoped, be read with more pleasure than a book giving solid
page after page of instructions.

Wherever a fact is mentioned as being taken from Holy Scripture, it will
generally be given in substance and not in the exact text; though the
reference will always be given, so that those wishing may read it as it
is in the Holy Scripture. The children are not supposed to memorize the
explanation as they do the Catechism itself, yet the teacher, having
once read it to them, should ask questions on it. The book may be used
as a textbook or catechism for the more advanced classes, and the
complete list of numbered questions on the explanations--given at the
end--will render it very serviceable for that purpose.

As the same subject often occurs in different parts of the Catechism,
explanations already given may sometimes be repeated. This is done
either to show the connection between the different parts of the
Catechism, or to impress the explanation more deeply on the minds of the
children, or to save the teacher the trouble of always turning back to
preceding explanations. The numbering of the questions and answers
throughout the Catechism, and the complete index of subjects and list of
questions at the end, will, it is hoped, make these comparisons and
references easy, and the book itself useful.
