Analysis of information sources in references of the Wikipedia article "Celestial marriage" in English language version.
Celestial marriage ... and polygamous or plural marriage are not synonymous terms.
This leads Swedenborg again to break with the long Christian tradition of there being no marriage in heaven (or at least of no weddings in heaven). Marriage in heaven is, however, different to that on earth. It is a meeting not of bodies but of minds. 'Marriage love,' he wrote, finds its source in the union of two people in one mind. In heaven, this is called 'living together', and they are not called 'two' but 'one'. Consequently two spouses in heaven are not called two angels but one angel. Because the heavenly communities consist of like-minded people, it is a matter of instant attraction: 'So at first sight they love each other most deeply, see each other as married partners, and enter into their marriage.' Heavenly weddings are followed by feasts that are attended by many.
