Origin & context

The story behind it

Word for word the phrase reads “into the ages of the ages”. It is a Hebrew-style way of saying “the greatest age” by repeating a word in the genitive plural, which gives the sense of “for ever and ever”.

It is found repeatedly in the Latin Vulgate, for example at the end of the doxology in Galatians 1:5, where Paul praises God. It echoes the Greek Bible phrase “eis tous aionas ton aionon”, which the Latin translators followed closely.

From there it became a standard ending of Latin liturgical prayers and the Gloria Patri, and so it is still known today to Catholics and to anyone who has sung or heard Latin church music.

Common mistakes

  • It is not “in the centuries of the centuries” in a literal calendar sense. Saeculum here means an age or era, and the whole phrase is an idiom for eternity.
  • The spelling is saecula saeculorum, with ae. Writing “seculum” or “saeculum saeculi” changes the form and the idiom.
  • It is usually the ending of a prayer. Many people confuse it with the full phrase “Amen”, which normally follows it.
