"The number of the ten virgins signifies the souls that have believed in Jesus Christ, symbolizing by the ten the only right way to heaven." - St. Methodios of Olympus
J. Pauli writes (Dictionary of Early Christian Literature, p. 422):
The Symposion seu convivium virginum, written in an elegant style and modeled on Plato's Symposium, gives a comprehensive introduction to various areas of Christian doctrine and attests to Methodius's vision of a completion of Platonism by Christianity. Ten virgins, taking part in a banquet in the garden of Virtue, each starting from a citation of scripture, praise not Eros but Parthenia as the perfect ideal of Christian life (though marriage is not rejected). The divine image in human beings is restored by chastity/virginity; the body then obeys the soul. At the end of the work, Thekla sings a marriage hymn in 24 strophes to Christ the bridegroom (an archetype of virginity: archiparthenos) and his bride the Church."
