James Wilson, 54, published the revelations in the St Bartholomew's C of E church bulletin, accusing Alyson, his wife of almost 20 years, of committing the most "heinous of crimes" by leaving him for another man.
A spokesperson for the church in Westhoughton near Bolton, described Mr Wilson's decision to publish details of personal family matters as "totally inappropriate".
However, the Daisy Hill, Westhoughton and Wingates team of churches said it continued to support James Wilson through his personal difficulties and the breakdown of his marriage.
The statement also said the copies of the bulletin were removed from circulation from all three churches immediately on discovery of the article.
Mr Wilson, a media sales consultant, and editor of the church magazine, wrote under the headline, Heartfelt Story: "Many of you have followed my life through this magazine and also my talks from the pulpit and I pray you have been able to reflect and take comfort from the goodness I impart about love, faith, marriage and family.
"I have always spoke fondly of my wife and my marriage and my kids to give you a lift, to give you a hope, to impart some love.
"Sadly I have to report to you my wife of 20-years recently ended our marriage and not in an amicable or hearty way. I am and have been in quite a mess. Well I am human too."
Explaining his decision to write the article, he said: "She was constantly out 'til all hours most nights, coming home with flowers, even a teddy bear that went to bed with her and sat on my bed 24/7. This soft pushover ain't being pushed over anymore."
"She would go missing for days at a time. It was blatantly obvious she was having an affair and she came home from him and got into my bed," he added.
"How cold is that dear reader? It's heartless, cruel and just not on. Talk about rubbing it in my face."
"I am bereft, numb, angry and disgusted with my estranged wife, a woman I have loved, worshipped and adored for 20 years.
"I understand relationships end...but to make the decision on your own, then go and jump into the first bed that comes along is wrong.
"Why I am sharing all this with you? Simply to make you think about your actions that only you choose to do. I can tell you that during my six years as warden to my own knowledge some 11 relationships have ended in adultery from our own church pews. We are supposed to be a beacon of light for Jesus. We are supposed to live life correctly."
