tldr summary - She (the former minister) tweeted (& instagrammed) a fairly homophobic few verses from the Bible, in the context of questioning the sponsorship of an LBGT Pride event by the Finnish Lutheran Church. (Of which she is a more-conservative member. Verses were Romans 1:24-27.)
That slim fact is surrounded by so much posturing, puffery, and canned quotes that most of the Roman Catholics I know are probably praying for the Lord to strike down the editor of the Catholic Herald with a column of fire from the sky.
Given how much nastiness - starting with women being very much the inferior sex - you can support with short quotes from the Bible, prosecuting her for the tweets strikes me as an idiotic counter-strategy.
