** Papal encyclicals are generally fairly long documents containing a variety of points about one or more issues. Some or all of these points are often about things that are beyond the scope of papal infallibility, dealing with things other than faith or morals, or being directed to some segment of the church. Traditionally, encyclicals are circular letters addressed only to the bishops of the Church. They tend to be discussions of some pressing matter at hand.**
