The first day of the Diaconate training focused on "The Liturgy of the Hours".
Here is what it looks like:
It is four volumes, comprised of 8140 pages of what St. Benedict called: "The Work of God".
It is the Prayer of the Whole Church, and it's purpose is to sanctify the day.
Everything in the Church has an Instruction with it. In Book 1 of the "Liturgy of the Hours", there is a "General Instruction" section, which starts on page 21. It ends on page 98. A brief overview which presents "The Mind of the Church".
When a man is ordained, he assumes a commitment to pray the Liturgy of the Hours faithfully.
