2. “ Who is worthy to open-and to loose-no man in heaven nor in earth"--5:2. The strong angel is emphasizing the important proclamation. The great voice is comparable to the announcement. The declaration no man in heaven nor in earth meant that it belonged only to the One on the throne to open it; no created being, terrestrial or celestial; no man in earth belonging to authorities of the earth; and, neither under the earth, or belonging to any order of humanity whether in authority as head or under subjection to powers of the earth, whether in the realm of living men or of the hadean domain of the disembodied spirits of men--no man, no created being was worthy or able, in finite limitations to open the book. The restriction neither to look thereon meant that they were not permitted to see or know what was in the book. To open meant to understand and reveal the significance.
