I have made the course of Instructions resemble as much as possible the oral teaching which a priest would give to a convert of reasonably good education; first, before receiving him into the Church, and, secondly, before admitting him to Holy Communion.
I hope this may sufficiently account for any abruptness and familiarity which may appear in the style.
I have introduced many things which are not necessary for all converts, and which will not be interesting to some; as, for instance, the rather minute explanation of Vespers in the Fourth Instruction of the Second Part. It is easy, however, to pass over what is not wanted.
I have put into an Appendix three subjects of which I thought it desirable to treat, but which did not come into the course of Instructions.
