“ Abba is not Hebrew, the language of liturgy, but Aramaic, the language of home and everyday life … We need to be wary of the suggestion … that the correct translation of Abba is ‘Daddy.’ Abba is the intimate word of a family circle where that obedient reverence was at the heart of the relationship, whereas Daddy is the familiar word of a family circle from which all thoughts of reverence and obedience have largely disappeared … The best English translation of Abba is simply ‘Dear Father. ”
