Hi, Mari. I remember some daily devotional booklets of other churches, such as "The Upper Room", or "Forward Day by Day", but neither of them are Byzantine or Catholic. From what I know, Byzantines find what you are looking for in many different sources. There are many Orthodox publications addressing the lives of the saints commemorated day by day, and there are multi-volume sets of biblical commentaries, such as those of St. John Chrysostom, but no daily reading devotional booklet based on the church calendar readings that I am aware of. It might be possible to cross-reference those readings to the commentaries of one saint or another. It would be a big job.
