I think the ************* issue is very superficial. I do not think the real reason why churches are declining in numbers is that it ******** the condemnation of *************, but rather, lies within a multitude of causes. The ************* issue may be one of them. However, there are also several probable causes why millennials are losing faith in Christ.
- lack of interest in the political-religious tangle and disaffiliation with both politics and religion
- commitment issues
- people who come from generations-old Christian families may seek a new religion/spirituality that is meaningful to them, or start identifying themselves as secular instead of nominal Christians.
- people who come from generations-old Christian families may get tired of the generations-old family traditions of baptisms, marriages, and life around the church.
- people who come from generations-old Christian families may think that there is truth elsewhere, not in the churches. Whether they find truth in science, philosophy, or religion, it is up to them where their paths may take.
I think racial and ethnic differences matter. For many ethnic minorities in America, they are very Christian, and Christianity is actively growing among these people. First-generation Chinese-Americans (Chinese immigrants) may encourage their kids to go to Christian parochial schools or attend Chinese Christian churches to meet new Chinese people who happen to be Christians. It has been published in the scholarly literature that many Chinese people have extrinsic motivations when converting to Christianity; that is, it's not the religion that attracts them, but the perceived social benefits that people get by socializing with people in one's own ethnic group in a land. Now, Chinese-Americans only make up a small minority of all Americans, so of course the polls won't show them.
I believe that if polls had taken the time and effort to do a thorough investigation of religion in regards to race, ethnicity, and other things, then they might create a more accurate picture of the American religious landscape.
