Thank you for sharing your compelling personal story. My cousin has also had to deal with declining enrollments and the downsizing of her Episcopal churches, although her current posting is enjoying a bit of a renaissance.
In the states people have been discussing the decline of Mainline churches and the rise of Evangelical mega churches for decades. We are now seeing a bit of a reversal since Covid, with disenchanted Evangelicals leaving churches for mainline denominations who are more accepting and less toxic in their politics.
