Did Jesus Christ ever have a family?
Yes He did have half-brothers and sisters, but He never married and had children.
Read these verses in Matthew 1:23-25
"Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us. Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife: And knew her not till she had brought forth her firstborn son: and he called his name JESUS".
You see that Mary was pregnent before she married Joseph, and they did not have children until after Jesus was born.
When Jesus began ministry and doing miracles the people were startled and said; Matthew 13:55-56
"Is not this the carpenter's son? Is not his mother called Mary? and his brethren, James, and Joses, and Simon, and Judas? And his sisters, are they not all with us?"
So the locals named the children of Mary by Joseph.
There were four brothers and at least two sisters. John says that these family members did not believe on Him.
John 7:5 "For neither did his brethren believe in him".
After Jesus died and came alive again, He ascended to heaven in the sight of many people, and there is no reference to Him living on earth or marrying and having children.
There are people who would like to believe that Jesus was not perfect and have written untrue fictional stories, but they are written for the purpose of trying to make Jesus less than God.
