I'll take it you mean Mark 3:35. But compare that to John 19:26-27: "When Jesus therefore saw his mother, and the disciple standing by, whom he loved, he saith unto his mother, Woman, behold thy son! Then saith he to the disciple, Behold thy mother! And from that hour that disciple took her unto his own [home]."
And so we disciples of Christ regard Mary as our Mother.
I'm not referring to the doctrine of Mother.
I meant 3:21 and 31. These verses indicate that Mary was not a "perfect disciple" as a poster above stated.
