how did the apostles creed get its name
The title Symbolum Apostolicum (Symbol or Creed of the Apostles) appears for the first time in a letter, probably written by Ambrose, from a Council in Milan to Pope Siricius in about AD 390 "Let them give credit to the Creed of the Apostles, which the Roman Church has always kept and preserved undefiled". But what existed at that time was not what is now known as the Apostles' Creed but a shorter statement of belief that, for instance, did not include the phrase "maker of heaven and earth", a phrase that may have been inserted only in the 7th century.
