So long as it is the truth - yeah you cant be sued.
So, stick the the facts in the unfortunate meeting ( after all there were witnesses ) and then in your opinion, you conclude these things make her unsuitable for whatever.
If you are £4k in debt - then you are known as "a man of straw" and not worth suing in the first place
and finally, defamation which what this allegedly could be - isnt or wasnt legally aided.
Try to keep away from 'I thought she was but she wasnt...'
and stick to 'what happened was .... '
Remember that if she comes up for a position/involvement in another church it is only fair for the pastor to say to her - " we have had these allegations, wodger say ? " I for example would be loudly unhappy if decisions were made about me with an email that I hadnt been allowed to answer but that of course is a completely different question
what is wrong with:
at this meeting it ws obvious that she had mental health issues
and it is clear I M O that these have to be sorted before she undertakes any long-term commitment for Church of the Saviour etc.
Perhaps you should discuss this with the head of your local church....
Depending on what she is saying .... if she is saying that St Gabriel has appeared to her saying s+x is OK with five year olds - then you have to act.
If however you are a wee free.... Lord Mackay had to answer to a synod that he had attended a Roman Catholic service - to wit the funeral of another judge. This was very bad to the wee frees but looked OK to us Romans.....
Perhaps discussing it with another church member is a decent first step
