You all know I have a thing about adjectives that are used in general theological discussion. Today I stumbled upon the following from the United Episcopal Church of North America:
Biblically Sound, Sacramentally Orthodox, Apostolically Valid
I’ll admit that my brain has been on holidays but I have no clue what the above means. But I am completely bamboozled by the last one: Apostolically Valid. Is there another form of validity?? Someone care to explain??

Valid in terms of their apsostolicity. e.g. the clergy are a valid part of the apostolic succession.
