I am presuming it was closed because the apologists cost money, as did the larger number of moderators that the previous forum had. It seems that the move to Discourse was to save money.
Also, the same questions tend to get asked here over and over, and it’s relatively rare for someone these days to have a question that an apologist hasn’t already addressed, either on here, or on the main CA site, or someplace else like EWTN site.
Also, I think we have a lot of good subject-matter experts on here that deal with Scripture questions, annulment questions, and questions requiring (name removed by moderator)ut from a priest or deacon (we have two priests and at least 2-3 deacons). So, between the past answers from apologists, and the subject matter experts who post on here, I’m not sure what more “Ask an Apologist” would add to this forum. Especially when a goodly number of posters who come here asking questions do not accept perfectly good answers that they are given.
If you want an apologist answer, there are likely CA live shows on radio that you could call into.
