Isidore of Seville

Why a “young man”? The resurrection of the dead, as the apostle declares, will be “unto the fullness of the measure of the stature of Christ,” that is, in the season of youth, which needs no further development and which is free from all defect, complete in every respect, having fullness of strength.

The sacredness of the Lord’s Day is apparent from the holy Scripture. This was the first day of the world. On this day the elements of the creation were formed. On this day the angels were created. On this day Christ rose from the dead. On this day the Holy Ghost came down from heaven on the apostles. On this same day the manna in the wilderness was first given.
