Conventional: Exalted praise, honor, beauty. Also, a halo of light surrounding a divine person (such as Christ or God) or surrounding the sun.
ACIM: Exalted praise, honor, beauty. Also, a shining radiance that emanates from holiness. Glory is of God, but the Course does not focus on acknowledging it in God. Rather, we need to see the glory that God gave our brother. This will reveal the glory that He gave to us, and allow our glory to shine upon the world, shining away the world’s illusions and illumining the minds of others.
