Hawker's Poor Man's Concordance And Dictionary 
This is a term we meet with in Scripture, taken from the former, and is applied to the Lord as solely his. But the church, considered from her union with Christ as part of himself, is also spoken of as glorious in him. Moses's song celebrates the Lord's glory in relation to his perfections. "Thy right hand. O, Lord, is become glorious: who is like unto thee, O Lord, among the gods? who is like thee, glorious in holiness, fearful in praises, doing wonders." ( Exodus 15:11) So the church, in consequence of her union with Christ, is said to be all-glorious within. ( Psalms 45:13) And the great object of redemption is said to be, that Jesus might present to himself a glorious church. ( Ephesians 5:27) But it should ever be remembered, that all the glory of the church is with an eye to Christ. If she be without spot, or wrinkle, or any such thing, and made comely, it is only "from the comeliness Jesus hath put upon her." ( Ezekiel 16:14)

glō´ri - us : The adjective "glorious" is used in the majority of cases as the translation of one of the nouns which are fully discussed in the article Glory , and the general meaning is the same, for the glorious objects or persons have the quality which is described by the word "glory," that is, they are honorable, dignified, powerful, distinguished, splendid, beautiful or radiant. It is worthy of note that in many passages in the New Testament where the King James Version has "glorious," the Revised Version (British and American) has the noun "glory." So among others in Romans 8:21 , the King James Version has "glorious liberty," the Revised Version (British and American) "liberty of the glory of the sons of God." The obsolete use of the word glorious in the sense of "boastful," "vain-glorious," "eager for glory," as it is used in Wycliffe, Tyndale and Bacon, and once or twice in Shakespeare, as in Cymbeline , I, 7, in the first speech of Imogen, "Most miserable is the desire that's glorious," and in Gower's Prologue to Pericles , 1, 9, "The purchase of it is to make men glorious" occurs at least once in the apocryphal books, Additions to Esther 16:4 the King James Version, "but also lifted up with the glorious words of lewd persons."
