This Modern Liturgy of the Hours conforms to the traditional 1960 Calendar of the period rendered into today's English for the use of the clergy and faithful.
“Prayer is the raising of the mind to God. We must always remember this. The actual words matter less.” - Pope John XXIII
On the Second Ecumenical Vatican Council:
"The Ecumenical Council will surely be, even more than a new and magnificent Pentecost, a real and new Epiphany, one of the many revelations which have been renewed and are continually being renewed in the course of history, but one of the greatest of all." —John XXIII. Apostolic Exhortation 'Sacrae Laudis' 1962
Canon 276 of the Code of Canon Law states all clerics are "obliged to carry out the liturgy of the hours daily." Then adds that the laity "are also earnestly invited to participate in the Liturgy of the Hours as an action of the Church."
