When Mason Remey took the road to Capernaum to visit `Abdu'l-Baha at Tiberius on the Sea of Galilee AB there announces that Mason is his son while also in the company of Mason's brother, Will. There are many references in MR writing to the lesser becoming greater and the notion of service, related to these passages. Matt 9:36 mirrors the statement of Baha'u'llah regarding adoption.
From the Book of Matthew:
Who Is the Greatest?
33They came to Capernaum. When he was in the house, he asked them, “What were you arguing about on the road?” 34But they kept quiet because on the way they had argued about who was the greatest.
35Sitting down, Jesus called the Twelve and said, “If anyone wants to be first, he must be the very last, and the servant of all.”
36He took a little child and had him stand among them. Taking him in his arms, he said to them, 37“Whoever welcomes one of these little children in my name welcomes me; and whoever welcomes me does not welcome me but the one who sent me.”
