Looking for an Online Collection of Pope St. Leo the Great Sermons in English by a Catholic Translator

In the post https://christianity.stackexchange.com/questions/109124/pope-leo-i-and-worshiping-towards-the-east-how-can-he-say-all-this-and-still-w , the OP makes reference to Sermon 27 of Pope St. Leo the Great. It links to the New Advent (Catholic Encyclopedia). The translator of sermons from Pope Leo I on that site is Philip Schaff, a Protestant theologian. After spending a considerable amount of time trying to locate online an English translation of Pope St. Leo's sermons (or even a sub-collection of them) by a Catholic translator and editor, I have come up empty-handed. So I ask--- QUESTION: Does anyone know where I may find a freely available English online collection of sermons by Pope St. Leo the Great by a Catholic translator? Thank you.
