Assuming I have the permission of those praying inside the church at a quiet time during the day (or when alone), is it licit to intone a Te Deum before the Blessed Sacrament? I mean… there are no particular graces or indulgences I wish to receive; to be honest, it’s simply a question about theology and canon law. The intense power of God has inspired me to do this, but I am not sure if it’s right. Is the intoned or sung recitation of the Ambrosian Hymn to be strictly reserved for special processions after Mass, and for special services of thanksgiving?
I suppose the question really is: do I need a priest, deacon, or religious present when singing this 5-6 minute piece in reverence before Christ in His True Body?
