Why is Mary considered the mother of God?
Luke 1:31-35
31 Behold thou shalt conceive in thy womb, and shalt bring forth a son; and thou shalt call his name Jesus. 32 He shall be great, and shall be called the Son of the most High; and the Lord God shall give unto him the throne of David his father; and he shall reign in the house of Jacob for ever. 33 And of his kingdom there shall be no end. 34 And Mary said to the angel: How shall this be done, because I know not man? 35 And the angel answering, said to her: The Holy Ghost shall come upon thee, and the power of the most High shall overshadow thee. And therefore also the Holy which shall be born of thee shall be called the Son of God.
Matthew 1:20-23
20 But while he thought on these things, behold the angel of the Lord appeared to him in his sleep, saying: Joseph, son of David, fear not to take unto thee Mary thy wife, for that which is conceived in her, is of the Holy Ghost. 21 And she shall bring forth a son: and thou shalt call his name JESUS. For he shall save his people from their sins. 22 Now all this was done that it might be fulfilled which the Lord spoke by the prophet, saying: 23 Behold a virgin shall be with child, and bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
Luke 1:43
43 And whence is this to me, that the mother of my Lord should come to me?
Catholic view (generated):
Mary is considered the mother of God in Catholic theology because she gave birth to Jesus, who is believed to be both fully human and fully divine. This title, "Mother of God" (Theotokos), emphasizes both Jesus' humanity and divinity, affirming his status as the Son of God. This belief highlights the unique role Mary played in the Incarnation, when God became man in Jesus Christ.
