The Relevance of the Letter to the Hebrews

I've wondered if there's something happening with the situation that the writer of Hebrews addresses. And the way that the writer frames it, I just think there's just something not repeatable about that. That is to say churches can have struggles and issues just like the Corinthians did in a modern context. Some of Paul's letters and what James has to say. First Peter as well, these texts are there's a high degree of relevance.
