We must pray to Me Holy Ghost, as to the Father and to the Son, or we do not pray in the fulness of the Evangelical development of the duty. To pray is to address our petition to God; but the God Whom we Christians worship is Father, Son, and Holy Ghost. Every petition to God simply, in our Liturgy, is a prayer to the Three Persons of the one Divine Nature; but this is not always distinctly before our minds, and I desire to bring it out with emphasis. The devotional treasures of the whole Church, and of all holy men who have composed petitions to the Third Person of the adorable Trinity, in Hymns as well as in Prayers, are spread out before us, and we can use them, at our will, in our private, family, and social devotions.
