"Advent is the harbinger to make way for the Queen-feast"

Henry Killigrew's sermon before the King on Advent Sunday 1666 is an example of how observance of Advent was recognised in Restoration Anglicanism.  The sermon begins with reference to the Gospel of the day:

Hosanna to the Son of David, blessed is he that cometh in the Name of the Lord, hosanna in the highest.

These words are the Acclamation of the people, at our Saviour's entering in Triumph into Jerusalem, and part of the Gospel appointed for this Day, the first Day of the Church's Year, as appears by the Cycle or Round of Collects begun this Day. Christians, with good reason; observing yearly, double sort of year, an Ecclesiastical from the Advent of our Saviour, as well as a Civil from the Return of the Sun. For the Times and Seasons of the Church are measured, her spiritual Growths fostered, not by the Sun in the Firmament, but by the Sun of Righteousness, not by Planetary Motions or Influences, but by the Star of Jacob, whose Dawn, or Rising upon the World we at this time solemnize.

Advent do's not imply that Christ is come, but coming; not his Presence, but his Approach; Christmas is the high Celebrity of his actual Arrival, this day only reports and noises abroad his drawing near. Advent is to Christmas, as John was to the Gospel, vox clamantis, the Herald or Harbinger that made way for it; so Advent is the Harbinger to make way for the Queen-feast to succeed with more Majesty, Royal Personages not only having Followers, but Fore-runners for greater State.

Killigrew also points to the Advent collect as defining the piety of Advent:

The Offices of the Church for this day best instruct us, how to welcome our Lord's Coming. What in the Collect we pray, let us set our selves to practice. To cast away the Works of Darkness now in this Mortal Life, in which Christ came to visit us in great Humility. What the People here do in my Text, let us transcribe and imitate; use their Acclamations ... Hosanna to the Son of David, and again, Hosanna. Reiterating and repeating these Ave's and Good Wishes to Christ in our Souls, a second, third, and fourth time ... 

Holiness and Righteousness make the Esclat or Splendour in Christ's Feasts; when Men's Hearts are full of Grace, then his Houses are hang'd, and his Tables prest with rich Provisions: 'twas not the Curious and Busy House-wifery of Martha, but the Pensive and Abstracted Faith of Mary that made the Entertainment at Bethany; and if we will Treat our Lord acceptably it must not be from the Shambles, or the Mercers; with the Cooks or the Tailor's skill; but with the Sacrifices of Obedience, and the Adornings of the Holy Spirit. Our Feasts upon Earth must resemble these they typify in Heaven, where Righteousness is the Robe, and the Contemplating and Glorifying of God, the Cheer and the Rejoicing.

Is there a contemporary relevance in this Restoration Advent sermon?  While Advent purists might want to question the focus on Advent as preparation for Christmas, this understanding both reflects and shapes a popular practice and piety, and ensures that Advent is related to the anticipation of and preparations for the festive season.  In other words, considerable pastoral wisdom is evident in this approach, rather than fighting - and inevitably losing - a rear-guard cultural action which insists upon a meaning and piety for Advent apart from and separate to the forthcoming festive season.  Rooting our preparations for Christmas in Advent ensures that the season both has a popular relevance and resonance and also offers the opportunity to deepen festive preparations, rather than being understood in sectarian fashion as a protest against such preparations.
