Universal letters

There are seven other letters that are not addressed to a specific church, but are more universal in nature.  They are the three letters that have been attributed to John, although there is no explicit mention of his name in them.  They are 1 John, 2 John, and 3 John, dating from 100-110 CE.  There are two letters that explicitly say that they are from Peter, 1 Peter and 2 Peter, written sometime between the late 60s and 130 CE.  Then there are the individually named letters from James, from the 90s-100 CE, and Jude, from 70-90 CE.  These letters have the purported authors as the apostles of the early Christian communities, John, Peter, James, and Jude.
