Last week the Evangelical Covenant Church… covchurch.org… (the church in which I was born, raised, and am a current member), dismissed First Covenant Church of Minneapolis from the denomination. First Cov is a historic church, built prior to 1900, and has interesting architecture with a balcony that wraps around the sanctuary on all four sides. First Cov sits on valuable property, being across the street where the Minnesota Vikings play in the southern portion of downtown Minneapolis.
The “sins” of First Cov have been obscured by distortions and omissions. Basically, the denomination wants uniformity as opposed to a fundamental concept, i.e., congregationalism, adopted by its founders. Because First Cov. envisioned having a same-sex marriage in its building at some point in the future (and there are other “reasons”), the denomination not only kicked out the church, but also revoked the ordination of its lead pastor for supporting same-sex marriage. The denomination also revoked the ordination of a retired pastor who presided over the same-sex wedding of his son.
Here’s some reading material, starting with an academic approach.
