John 20:17

17Jesus said to her, “Do not cling to me, for I have not yet ascended to the Father; but go to amy brothers and say to them, b‘I am ascending to my Father and your Father, to cmy God and your God.’”

Galatians 3:26

26for in Christ Jesus dyou are all sons of God, through faith.

Hebrews 2:10-15

10For it ewas fitting that he, ffor whom and by whom all things exist, in bringing many sons gto glory, should make the hfounder of their salvation iperfect through suffering. 11For jhe who sanctifies and kthose who are sanctified lall have one source.
Greek  all are of one
That is why he is not ashamed to call them nbrothers,
Or  brothers and sisters. The plural Greek word adelphoi (translated “brothers”) refers to siblings in a family. In New Testament usage, depending on the context, adelphoi may refer either to men or to both men and women who are siblings (brothers and sisters) in God’s family, the church; also verse 12
12saying,

p“I will tell of your name to my brothers;
in the midst of the qcongregation I will sing your praise.”
13And again,

rI will put my trust in him.”
And again,

sBehold, I and the children tGod has given me.”
14Since therefore the children share in flesh and blood, he himself likewise upartook of the same things, that vthrough death he might wdestroy xthe one who has the power of death, that is, the devil, 15and deliver all those who ythrough fear of death were subject to lifelong slavery.
