How much older wa John the Baptist than Jesus?

Answer 1

Six (6) months (Luke 1:36)

According to Luke 1:36, Elizabeth was six months pregnant with John when Jesus was conceived in Mary by the Holy Spirit, so John would have been six months old when Jesus was born.

Answer 2

John was about 6 months older than Jesus.

(Luke 1:34-36) 34 But Mary said to the angel: "How is this to be, since I am having no intercourse with a man?" 35 In answer the angel said to her: "Holy spirit will come upon you, and power of the Most High will overshadow you. For that reason also what is born will be called holy, God's Son. 36And, look! Elizabeth your relative has also herself conceived a son, in her old age, and this is the sixth month for her,

Answer 3

Luke's Gospel says that John the Baptist was born miraculously to Elizabeth in her old age, six months before Jesus was born to Mary. The problem is that only the author of Luke's Gospel seems to have known anything about John's infancy or been aware of a family relationship between Jesus and John the Baptist, if such a relationship existed. Even the name of John's mother raises doubts as to the historicity of events that supposedly occurred many decades before Luke was written. John Shelby Spong (Born of a Woman) says he is suspicious because Elizabeth in Hebrew would be Elisheba', a name that appears only once in the Old Testament, as the wife of Aaron, brother of Moses. Luke 1:5 describes Elizabeth as the daughter of Aaron, so the author must have had Aaron and Moses in mind when he wrote his Gospel.

Until the historicity of this part of Luke's Gospel is resolved, we must acknowledge we really know nothing about the family of John the Baptist, including whether his mother was really related to Mary or whether John was either older or younger than Jesus.
