"Is there a human issue that isn't a faith issue?"
I think there is/are. That is not to deny that they are about God and godliness.
Too much of what is "observation and reason" is attributed to faith, as for example, the common good. Religion has made "natural law" a matter of religion and faith, defined it ideologically and elevated it to immutable truth, then to doctrine and imposing it - fossilized, intransigent, divisive.   Sadly, many human issues are coopted by religions and are wrapped up in ideology which, in turn is imposed as if they are "commandments" of religion. Often they become entangled in the ideological dimension of religion and become instruments of domination,  and of exclusion, 
I repeat often my contention that Jesus did not create love/compassion. It has its origin in "the image and likeness of God", in creation. Jesus raised it, asks for more, for us to go further as we return to the Creator. 
Jesus as "teacher" is within the line of great philosophers.
