Again -- and for some time -- we have the eccentric Universalist dating, and only a single lection. I suspect the Universalist collect is from Martineau, as I've only found the phrasing in a period Unitarian congregational worship-book and a (later) Unitarian work of daily prayer. Seems better fit for a baptism or the Feast of the Baptism of Jesus, which has already past in most calendars. (The lesson is the Woman at the Well.)
I'd stick to the Free Church propers this week.
Free Church Book of Common Prayer (1929)
Almighty and everlasting God, mercifully look upon our infermities, and in all our dangers and necessities stretch forth thy right hand to help and defend us; through Jesus Christ our Lord. Amen.
Epistle: Rom. xii, 16b-21 (end).
Gospel: Matt. viii, 1-13
A book of prayer for the church and the home (Universalist, 1866)
Fourth Sunday after Christmas
O God, our heavenly Father, who by thy best-beloved Son hast opened to us a fountain of living water; grant, we pray thee, that we may so drink of this water as to be refreshed in all our weariness of spirit, to be strengthened for thy blessed service, and to have within us a well of water springing up into everlasting life.
Gospel, St. John iv. 5.
