"Felicitas Perpetua" = eternal bliss – and also the names of the two saints the Catholic Church remembers and celebrates every year on March 7, SS Felicity and Perpetua, who were martyred together in Carthage in 203. Their story is not well known, but their names are familiar to older Catholics as one of a few same sex couples that were once listed in the Eucharistic Prayer of the Mass. These paired names are an echo of their place in the ancient rite of adelphopoeisis (literally, "making of brothers"), the liturgical rite once used to bless same sex unions in Church.
As two women martyred together, and from the kiss of peace which they exchanged at the end, they are frequently described as a lesbian counterpart to Sergius and Bacchus. This is inaccurate. Their relationship was not primarily one of lovers in the modern sense, but of mistress and slave. But that description is also inaccurate to modern ears, as it overlooks the very different status of women,and the very different nature of marriage relationships, in Roman times. In the journal kept by Perpetua (from which we know the story), she never once even mentions her husband. It is entirely possible (even probable?) that whatever the nature of her sexual life, Perpetua's emotional involvement with Felicity may have been more important than her relationship with her husband.
