Dear Central,It's never easy to leave one's friends and start over again in an unfamiliar town. The decision to make this change was a tough one but we feel it was the right one. I wanted to thank all the young people that gave up their time and energy in pursuit of a greater relationship with our Lord. You are very special individuals. Continue to seek after the Lord and live the Christian life. We love you. I also wanted to take this opportunity to thank all of Central for the love and kindness that has been extended to my family. The time that we have been blessed to spend with you as a part of the Central family has been special to us. You will always have a special place in our hearts. Please continue to keep our family in your prayers as we will keep you in ours. It has been a pleasure and joy serving the Lord with you.
In Brotherly Love, Matthew Winkler
This is not a smoking gun. As a pastor leaving a congregation, he would naturally be the one to write the letter, and he's clearly speaking for his entire family (e.g., "we," "our," "us"). I don't see any indication that he's a power-tripper.
I think in the CoC,the female is to remain silent.So,he probably wouldn't sign her name to it.(At least that's what my former CoC parents told me)
