Who impregnated Mary?
Would it be Jesus' father?
Now the birth of Jesus Christ was as follows: After His mother Mary was betrothed to Joseph, before they came together, she was found with child of the Holy Spirit. (Matthew 1:18 NKJV)
But while he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, "Joseph, son of David, do not be afraid to take to you Mary your wife, for that which is conceived in her is of the Holy Spirit." (Matthew 1:20 NKJV)
And the angel answered and said to her, “The Holy Spirit will come upon you and the power of the Highest will overshadow you, therefore, also, that Holy One who is to be born will be called the Son of God. (Luke 1:35 NKJV)
The Holy Spirit is not a person, it is the power of the Most High that can be poured out on a person.
