In one of his brief little tracts, Percy Dearmer wrote explained for his day (the turn from the 19th to the 20th century) the spiritual system of the prayer book. Of course, he’s referring to the English 1662 BCP, but most everything he says still holds for the American ’79 as well:
A CHRISTIAN’S LIFE ACCORDING TO THE
Let us see, then, what the Prayer Book system will be when we have come back into the habit of carrying it out.
The Churchman is helped by the grace of God all through his life, from the cradle to the grave. He is baptized as a little child, and thus brought into the [28/29] Holy Catholic Church and made a member of Christ. As soon as he is old enough to understand, he is taught the Catechism diligently, thoroughly, regularly, from week to week, while his elders sit by and listen—for they are expected to be present.
When he has come to years of discretion, and is no longer a little child, he is brought to the Bishop to be fortified by Confirmation. After Confirmation he becomes a regular communicant, going to the Lord’s Service every Lord’s Day, indeed on Holy-days as well as Sundays. [* The Prayer Book provides Collects, Epistles, and Gospels for the red-letter Saints’ Days just the same as for Sundays.]
Thus at Baptism he begins his spiritual life, just as he begins his natural life at birth. [* See the 3rd chapter of S. John’s Gospel, where our Lord explains this as being “born again.”]
At Catechizing he learns about his spiritual life.
At Confirmation he is strengthened in his spiritual life.
At Communion he is given spiritual food to support his spiritual life, just as at ordinary meals he is given common food to support his natural life. [* See the 6th chapter of S. John’s Gospel, where our Lord says that except we are fed with the Body of Christ we have “no life,” that is no spiritual life, in us.]
If he is married, he comes for the blessing of the Church; and at the end of the Marriage Service a rubric tells the newly-married pair that they ought then, or as soon after as possible, to make their Communion. If there are any children, the mother comes to be Churched; and then the little one is brought to Baptism, and the “Occasional Services” are begun over again for another little Christian.
Lastly, when illness comes, the Church is there with her blessing once more for his Visitation, Absolution, and Communion; and at the end of all she receives his body for the last time within her walls, and commends his soul to God in the Burial of the Dead.
 Thus the events in a Christian’s life have taken us through a considerable part of the Prayer Book—the part that lies between the Thanksgivings and the Psalter.
“ALL THE DAYS OF MY LIFE”
Now let us look at the rest of the Prayer Book—the parts that concern the everyday life of the Christian, viz.:—
(1) The Kalendar (including the Lectionary).
(2) The large section from Mattins to the end of the Prayers and Thanksgivings.
(3) The Psalter.
How does the Church of England expect you and me to worship God from day to day? More than we most of us do. The bad habits of many generations have left us far behind this Christian ideal, and often we cannot live up to it if we would. Holy-days, for instance, used to be real holidays, when all the people had a rest; and then it was easier to come to church. But Oliver Cromwell made people work on these days, and took away the people’s holidays; and so it has been more difficult to go to church ever since.
Still, most of us could worship God more than we do. We might come to church before work begins, for instance, on Holy-days, and many can often come on ordinary week-days also.
Here, at any rate, is what the Prayer Book expects of us:—
1. Every day of the week. Morning Prayer in the morning and Evening Prayer in the evening, “that the people (by daily hearing of holy Scripture read in the church) might continually profit more and more in the knowledge of God.” [* The Preface “Concerning the Service of the Church.” See also the Order at the end of this Preface; and notice how often the word “daily” comes in the Prayer Book.]
2. Wednesdays and Fridays.  The Litany in addition to Mattins and Evensong.
3. Holy-days, i.e., the Saints’ Days, etc., “to be observed.” The Holy Communion (see the Collects, Epistles, and Gospels provided for these days), and Catechizing, in addition to Mattins and Evensong.
4. Sundays. In addition to the above (Mattins, Litany, Holy Communion—with the special Collect, Epistle and Gospel of the Sunday—Evensong, Catechizing) a Sermon is ordered to be preached on Sunday during the Communion Service by Canon 45.
Some special days are further marked out. The Great Festivals (Christmas, Easter, Ascension, Whitsunday, Trinity Sunday) have Proper Prefaces at Holy Communion. Ash Wednesday has an extra service of penance called the Commination. Four times a year there are three Ember Days, which have special Collects, so that people may pray for those who are to be ordained on the following Sunday. Other “Prayers and Thanksgivings” are provided for special occasions, notably the beautiful Prayer for ALL Conditions for use on the mornings when there is no Litany, and the Prayer for Parliament for use during the Session; and furthermore, the Athanasian Creed is set down on certain Festivals.
Add to these the Forms of Prayer to be read daily at sea, which come after the Psalter, and the Ordinal (i.e., the Services for the Ordination of Deacons and Priests, and for the Consecration of Bishops), and we have completed our survey of the Prayer Book.
THE IDEAL BEFORE US
Is it not a great ideal of Christian life and worship? Shall we not all be better and stronger men when we take better advantage of our opportunities? Will not the Church of England be indeed a great and noble [31/32] Church when all who belong to her are regular communicants, when the parish church of every place is thronged with devout worshippers day after day, and when the children of England are all thoroughly taught the splendid Doctrine and Duties of the Catechism?
It is a sad and humiliating thought that, while a few centuries ago all Englishmen belonged to the fellowship of the one Church, and all partook of the life of our Lord in the Sacrament of His Body and Blood, now England is full of petty divisions and miserable quarrelling, while the masses of the people are not even communicants. They belong to the Church, but they do not understand her, and so they are not faithful to her, and have little real love for Christ in their hearts. We have, therefore, enormous arrears to make up. We must pray more, worship more, teach others more, and thus lead the way, by our own loyalty, to a great revival of Christianity in our land.
Shall we not succeed? Through the neglect of past years the Church has become like a missionary in a strange land. But as we love God more and love our neighbour more, and in this spirit of love and devotion carry out the half-forgotten rules of the Prayer Book, we shall lead the people back from their Babylon, and build again the walls of Jerusalem.
The whole tract is available on Project Canterbury but this is the heart of it.
