Q. 1. Where any of the Apostles married? If so, how come we never hear about their wives?
A. 1. According to Mark 1:29-34, Luke 4:38-39 and Matt 8:14-15, Peter was married. Those Bible passages make reference to Jesus healing Peter's mother-in-law who was suffering from a fever.
It is believed that all the other Apostles, with the exception of John who was too young, were married when they joined Jesus' ministry. The Bible does not make much reference to their being married, most likely because they lived celibate lives after they joined Jesus. At the same time, it is believed that the Apostles provided the needs of their wives through their occupation of fishing.
In 1 Corinthians 9:5, Saint Paul makes reference to the marital status of the Apostles. He said, "We have the right to take a believing wife with us like the other apostles..."
Old Church documents indicate that in the earliest centuries of the Church's history, it was commonplace for the clergy to be married. This changed by the fourth century. When the Council of Elvira was held in Spain, it was clear by then that celibacy was commonplace among the clergy members.
