I am the new choir director at my church. We have never had one before, only choir presidents. 2 years ago I was asked by the deacon over the choir if I would learn how to direct a choir. I did considered taking the position and I learned as much as I could via online resources about directing a choir. The more I learned the more comfortable I became about officially accepting the position. So after praying about it and talking with my Pastor he instructed me to go ahead and work with the choirs this month (November) and be sure to make my expectations known to the choir president well in advance of rehearsal. Soon after, one of the choir presidents approached me and said in a pleasant tone that she had been informed by the deacon that I will be choir directing. I also spoke with her on several different occasions to further inform her on my duties as choir director. On the night of rehearsal, as I introduced myself to the choir and the choir director, the president rudely intervened saying I DONT KNOW WHATS GOING ON! AINT NOBOBY TOLD ME NOTHING! I was very shocked at her behavior. We spoke several times and she never said she had a problem with it. We know each other fairly well and have talked outside of church. She even has my number and could have called with any concerns she had. The other choir members accepted it very well. They asked for my opinion and suggestions several times but the president always disagreed with everything that I said (and she was wrong every time). She was very rude and disrespectful. How should I handle this situation to ensure that it will not happen next month?
