JESUS - Hebrews 2:11

Both the one who makes people holy and those who are made holy are of the same family. So Jesus is not ashamed to call them brothers and sisters. 

Both the one who makes people holy 
Hebrews 13:11-12  The high priest carries the blood of animals into the Most Holy Place as a sin offering, but the bodies are burned outside the camp. And so Jesus also suffered outside the city gate to make the people holy through his own blood.

and those who are made holy 
Ephesians 5:25-27  Husbands, love your wives, just as Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless.

So Jesus is not ashamed to call them brothers and sisters 
Matthew 28:10  Then Jesus said to them, "Do not be afraid. Go and tell my brothers to go to Galilee; there they will see me."
Matthew 12:49-50  Pointing to his disciples, he said, "Here are my mother and my brothers. For whoever does the will of my Father in heaven is my brother and sister and mother."

Mark 3:34-35  Then he looked at those seated in a circle around him and said, "Here are my mother and my brothers! Whoever does God's will is my brother and sister and mother."
Romans 8:29  For those God foreknew he also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers and sisters.
