A Christian intelligentsia can help contribute ideas for solutions to the problems Christians face in modern times.
Also, realizing the importance of discussing the work of modern Christian thinkers and their work helps to unite Christians by creating a shared theme of discourse--something interesting and worthwhile to talk about around likeminded people that sheds light on who they are, what problems they face, and where they are going.
Part of creating and maintaining a modern Christian culture involves identifying and promoting a Christian intelligentsia. An intelligentsia involves thinkers who help shape a way of thinking in society and provide guidance in solving problems in relation to that way of thinking. An intelligentsia can be helpful because they can figure out possible solutions to problems that members of a group might generally find too confusing to figure out without having spent extensive time considering them or having a higher degree related to the topics.
There are already individuals in society who could be considered to be or are already recognized as members of a Christian intelligentsia. However, their number should be increased and more effort should be put into promoting their work. Also, realizing the importance of discussing the work of modern Christian thinkers and their work helps to unite Christians by creating a shared theme of discourse--something interesting and worthwhile to talk about around likeminded people that sheds light on who they are, what problems they face, and where they are going.
In terms of finding and promoting new members of a modern Christian intelligentsia, a way to tell if someone should be read or listened to by many would be by reading their work or hearing what they have to say and being struck by it. This could take the form of connecting with their ideas on a deep level and seeing how prudent their ideas are for solving one or more problems Christians face today. A Christian can then share this person's work through social media, through a faith group, or by word of mouth in general. This would help generate interest around the new thinker and their work. Once this new thinker and others like them gain attention and esteem on a larger scale, Christians also want to promote them together with other thinkers who are already regarded as members of a Christian intelligentsia. Promoting them together in the category of an intelligentsia gives them more credibility. People can also be interested by the idea of an intelligentsia. Interest and credibility help a larger audience learn more about what these thinkers have to say and be better able to share their thoughts and solutions.
