We, as Catholics are not permitted to believe anything of our own will, nor to choose what someone has believed of his. We have God's apostles as authorities, who did not themselves of their own wills choose anything of what they wanted to believe, but faithfully transmitted to the nations, the teachings of Christ.
Isidore of SevilleBaptism is not the work of man but of Christ, and this sacrament is so holy that it would not be defiled, even if the minister were a murderer.
Isidore of SevilleTolle numerum omnibus rebus et omnia pereunt.Take from all things their number and all shall perish.
Isidore of SevilleTshe suffering of adversity does not degrade you but exalts you. Human tribulation teaches you; it does not destroy you. The more we are afflicted in this world, the greater is our assurance for the next. The more we sorrow in the present, ..the greater will be our joy in the future.
Isidore of SevilleThe name of medicine is thought to have been given from 'moderation', modus, that is, from a due proportion, which advises that things be done not to excess, but 'little by little', paulatim. For nature is pained by surfeit but rejoices in moderation. Whence also those who take drugs and antidotes constantly, or to the point of saturation, are sorely vexed, for every immoderation brings not health but danger.
