Every year, the choir has sung the response (244 in Ritual Song) "You have put on Christ, in him you have been baptized. Alleluia" after each baptism at the Easter Vigil. It's by Howard Hughes, and sounds ridiculous. I detest it! Since the people who run the RCIA program like the words, I need to find a musical setting that keeps the words, but has some dignity to it. Do any of our esteemed members know of another setting?
I like the Byzantine chant version used in Melkite churches. This PDF is a simplified version set to English words, but you might make something more decorated out of it.
The chant «Omnes qui» is a Communion, and is surely not intended to be sung at Baptisms right after the immersion. But there are far worse things than using a Communion in that way...
Look at the English-language settings of this from Russian Orthodox/OCA sources. Easy four-part harmonizations. Goggle "As many as have been baptized into Christ" It replaces "Only Begotten Son of God" in the liturgy on certain feasts. Here's one: http://www.theologian.org/pdf/harmonized/AsManyBaptized.pdf
I guess you could just change the words to suit the RCIA folks.
Ditto, Charles, to MJB's suggestion. That's what we've used for a couple of years. Some arrangements have a lot of doubling among voice parts, which one can discreetly reduce to SATB easily.
Isn't it OK to just sing a festive Alleluia after each Baptism? That's what we do. It's short and suits our English/Spanish liturgies because it's the same word in both languages. But apart from language, it seems an appropriate acclamation for one just Baptized, especially on Easter.
The Communion antiphon for the Baptism of our Lord, Omnes qui in Christo baptizati estis, has a text very similar to the text you have been singing: "All you who have been baptized into Christ have clothed yourselves with Christ, alleluia."
The Latin can be found in the Graduale Romanum. An English adaptation can be found in the part of The American Gradual currently accessible on the Musicasacra Web site.
