Abba

Abba - (Easton's Bible Dictionary)

This Syriac or Chaldee word is found three times in the New Testament (Mark 14:36; Rom. 8:15; Gal. 4:6), and in each case is followed by its Greek equivalent, which is translated "father." It is a term expressing warm affection and filial confidence. It has no perfect equivalent in our language. It has passed into European languages as an ecclesiastical term, "abbot."

Abba - (Webster's 1828 Dictionary)

AB'BA, n. In the Chaldee and Syriac, a father, and figuratively a superior. appen.

In the Syriac, Coptic and Ethiopic churches, it is a title given to the Bishops, and the Bishops bestow the title, by way of distinction, on the Bishop of Alexandria. Hence the title Baba, or Papa, Pope or great father, which the Bishop of Alexandria bore, before the Bishop of Rome.
