All the disciples of Christ have not the same degree of honour in this world, nor in the next; because all do not make an equal use of the graces they receive. Some are in the first rank, as apostles; then those, to whom the gift of prophecy has been committed; then doctors each exalted according to his merit. For there are many mansions, and many degrees of glory, in the house of the heavenly Father. (Calmet)
For there is one brightness of the sun, another of the moon, and another of the stars; for star differeth from star in brightness. (1 Corinthians xv. 41.)
