Tempus per Annum - Domine in tua misericordia

I am currently working on volume 3 of my collection of motets Tempus per Annum, my collection of motets for the Church's year. This volume covers the half of the Sundays in Ordinary Time. I have just finished number 7, Domine, in tua misericordia, the Introit for the 7th Sunday in ordinary time, set for 5 -part choir (SATBB).
