In almost every prayer that Jesus utters in the New Testament, He addresses God as Father... This represents a radical departure from Jewish custom and tradition. Though Jewish people were given a lengthy number of appropriate titles for God in personal prayer, significantly absent from the approved list was the title “Father”… The serious reaction against Jesus by His contemporaries indicated that they heard in His addressing God as Father a blasphemous utterance by which Jesus was presuming, by this term of address, a certain equality that He enjoyed with the Father.
