The Roman law held that by adoption a civil or legal kindred was established between the parties, which in many respects had the same effects as natural kindred. To this as a general principle the canon law adhered. But since, in proportion to the degree in which the adoptive was assimilated to the real relationship, impediments to marriage were multiplied, it became necessary in the interest of Christian society to restrict the effects of adoption within reasonable limits.
