As a prayer, I found this to be a bit awkward on a couple of levels. As a Christmass meditation, though, it's a wonderful way to begin the Twelve Days of Christmass. spt+
O Merciful, Eternal God, heavenly Father, we Thy children thank Thee from the inmost of our hearts, that Thou hast so faithfully kept Thy promise and didst turn to us They heart of fatherly love, in sending to us the highest Good, Thine only begotten Son, for our Savior, and making us acceptable in Thy Beloved.
O Christ Jesus, Thou eternal Son of God, we honor, praise and magnify Thee, that Thou on this festal day didst become our brother and Emmanuel, that is, God with us; that out of unspeakable love, Thou hast befriended us and clothed Thyself with the garb of our flesh and blood. In no wise didst Thou assume the nature of angels, but the seed of Abraham, our human nature, that is but earth and ashes and dust, Thou didst so honor as to unite Thyself with it personally, inseparably and eternally. Thou wast conceived without sin and born into this world by a pure and chaste virgin; thus Thou didst sanctify and consecrate our sinful and impure conception and birth, that it may not be harmful to us, we being by nature the children of wrath, conceived in sin, and flesh born of flesh. Thou wast born in a stable and didst lie in the manger on straw in abject poverty and Thou didst not take offense, so that, having enriched our souls, Thou couldst make us great lords in Thy heavenly mansion. Thou hast humiliated Thyself in order to exalt us; Thou didst come down upon this earth, that we might go up to Thee in heaven.
O God, The Holy Spirit, our highest teacher and comforter, we today offer Thee the sacrifice of our lips, heartily thanking Thee that Thou hast revealed unto us this great "mystery of godliness"; and as the angels proclaimed and chanted it to the shepherds on the field, even so dost Thou proclaim it to us through Thy Word and Thy servants. Glory be to Thee, O God, Father Son and Holy Spirit in the highest, peace on earth and good will towards men. Grant, O faithful God and Father that sharing in the benefits of the human birth of Thy dear Son and delivered from the evil results of our sinful birth, we may be and remain newborn children of Thy grace and heirs of Thy kingdom. O dearest Jesus mine, Do Thou in my heart's shrine, As on a bed incline, That I be ever Thine.
Do Thou, O God the Holy Spirit, bring it about that this our Savior be spiritually born and grow in us at present and ever after. Help us also to rejoice over this birth and find comfort in it amidst all temptations, to suffer all things patiently and to gain the victory, so that we may honor, praise and glorify Thee with all the angels of God, here in time and hereafter in eternity. Amen.
