Abelians, or Abelonians
A sect which arose in the diocese of Hippo, in Africa, in the fifth century. They regulated marriage after the example of Abel, who, they pretended, was married, but lived in a state of continence: they therefore allowed each man to marry one woman, but enjoined them to live in the same state. To keep up the sect, when a man and woman entered into this society, they adopted a boy and a girl, who were to inherit their goods, and to marry upon the same terms of not having children, but of adopting two of different sexes.
