Today's Collect Prayer presents a good illustration of the perspective of Morning and Evening Prayer. The author (Thomas Cranmer) begins by identifying who is doing the praying: "This thy family." Only afterwards does he then expand the prayer to matters of the "thy holy Church", and finally to persons those outside the Church that "should be converted and live." Indeed, he constructs this Collect as three separate prayers, each with its own 'amen'.

Let it never be said that Morning and Evening Prayer is not the bread and butter of Anglican piety or that the liturgy is not designed primarily for use in the home.  

In most churches, the kind of "Altar Call" one typically hears is this: "Come if you hear Jesus calling." It is typically made at the end of a worship service, after the preaching, prayers and music; when the hearers are most likely to be emotionally receptive.

In the Book of Common Prayer, there is also a form of Altar Call but it is significantly different, reflective of Reformed doctrine and practice. The main difference is that it comes not at the end of the service but at the beginning, immediately following the Confession of Sin. It is not an emotional appeal to unregenerate "goats". Rather it expects that those to whom the gift of repentance is given are also given the gift of faith; to hear God's Word, to pray and to respond.

"Minister. O Lord, open thou our lips.
Answer. And our mouth shall show forth thy praise.
Minister. O God, make speed to save us.
Answer. O Lord, make haste to help us."

Then it quotes from Hebrews 3:

"... To day if ye will hear his voice, harden not your hearts : as in the provocation, and as in the day of temptation in the wilderness; When your fathers tempted me : proved me, and saw my works. Forty years long was I grieved with this generation, and said : It is a people that do err in their hearts, for they have not known my ways. Unto whom I sware in my wrath : that they should not enter into my rest."

Jonathan Edwards once said “The principle evidence of life is motion; so the principle evidence of saving grace is holy motion.” In other words, as the evidence of being physically alive is in breathing, moving, and acting, so also is the evidence of being spiritually alive in movement toward the things of God and the spiritual fruit that appears. As Jesus said, “The tree is known by its fruit” (Matt. 12:33).

Christianity, as defined in the Reformation is not for those that sit to merely see or listen, but it is for those that move, who rise up from their seats, raise their helpless hands and voices in response to God's Word, and do that for which He has purposed them.

In this light, based on a fair appraisal of the effects of our Morning and Evening Prayer, we understand its closing words to mean that Christ supplies every need both here and hereafter, and that we should have full assurance that He will fulfill them in as we... together... labor for the fruit that He intended.  

"ALMIGHTY God, who hast given us grace at this time with one accord to make our common supplications unto thee; and dost promise, that when two or three are gathered together in thy Name thou wilt grant their requests; Fulfill now, O Lord, the desires and petitions of thy servants, as may be most expedient for them; granting us in this world knowledge of thy truth, and in the world to come life everlasting. Amen.
