Liturgy of the Hours. What I'm talking about is my own Sunday reading.
On Sundays, (and that means from Evening Prayer 1 to Evening Prayer 2), I put aside whatever non-Catholic books I may be reading. On Sunday, I read only Catholic books from Catholic publishers, (or the Catholic imprints of mainstream publishers.)
The book can be fiction or non-fiction, but it absolutely MUST be something I'll want to carry into the next week. Dull, dry books are not welcome!
This may seem like a restriction, but it is actually an enhancement of the most beautiful, precious day of the week. And, as a bonus, I find that I enjoy the non-Catholic books all the more for having put them aside for those 24 hours.
