BUG: Missing parallel resources

As I have both the Protestant and the Catholic version of ANF 08 I can consistently count on at least of a pair of parallel resources. In this case there is no parallel passage, probably because there is only page number not a data type. This surprises me because the text is in the first volume of Migne (Greek). I expect parallel resources to be reliable for the early church/apostolic fathers.

Orthodox Bishop Alfeyev: "To be a theologian means to have experience of a personal encounter with God through prayer and worship."; Orthodox proverb: "We know where the Church is, we do not know where it is not."
