PRECISELY!!
It is, after all, the responsibility of the church of Christ to be "up to date" with popular morality.
Te decline in membership and attendance is caused by quite the opposite. That is, the decline in morality and Biblical teaching in the official church. They double down on the road to hell.
The more they talk about it, the more people leave. We left over it. The problem became that the church could not read through the entire Bible because there were too many parts that offended them. The non-denom church we attend now did a sermon series on Romans. The UMC church we attended could not do that.
