Yes.
"And as he was yet speaking, behold a bright cloud overshadowed them. And lo, a voice out of the cloud, saying: This is my beloved Son, in whom I am well pleased: hear ye him."Matthew 17:5
I certainly hope you're not attempting to suggest this passage has anything to do with Mary??
I post the passage in context for the reader.
1Six days later Jesus took with Him Peter and James and John his brother, and led them up on a high mountain by themselves. 2And He was transfigured before them; and His face shone like the sun, and His garments became as white as light. 3And behold, Moses and Elijah appeared to them, talking with Him. 4Peter said to Jesus, “Lord, it is good for us to be here; if You wish, I will make three tabernacles here, one for You, and one for Moses, and one for Elijah.” 5While he was still speaking, a bright cloud overshadowed them, and behold, a voice out of the cloud said, “This is My beloved Son, with whom I am well-pleased; listen to Him!” 6When the disciples heard this, they fell face down to the ground and were terrified. 7And Jesus came to them and touched them and said, “Get up, and do not be afraid.” 8And lifting up their eyes, they saw no one except Jesus Himself alone. Matthew 17:1-8 NASB
So who was the mother of the Son of God?
Somebody, other than Mary?
