I grew up a second-generation immigrant in the outback of the Western Canadian prairies. Our family was poor economically, subsistence farmers, with the necessities but seldom with much more. My father and mother were charitable to a fault and tried to instill that in us. However, given our own poverty, understandably we did not have much of a vision in terms of social justice. We were the poor.
Growing up in this way can deeply ingrain certain instincts and attitudes inside you, some good, some bad. Positively, you grow to believe that you need to work hard, that nothing is given to you free, that you need to take care of yourself, and everyone else should do the same. Ironically, that very ethos can blind you to some major truths regarding the poor.
I can testify to this. It took me many years, work that took me over many borders, some firsthand encounters with people who didn't have the basic necessities of life, and countless hours in theology classrooms before I even became aware of some of the basic biblical and Christian truths regarding the poor.
Now I am struggling to live them, but at least I accept that they are non-negotiable for a Christian, irrespective of denomination or political persuasion. In brief, as a Christian, we are given a non-negotiable mandate to reach out to the poor in compassion and justice. Moreover, this mandate is just as non-negotiable as keeping the commandments, as is clear most everywhere in Scripture.
Here is the essence of that mandate ...
As well, most of us have been raised to believe that we have the right to possess whatever comes to us honestly, either through our own work or through legitimate inheritance. No matter how large that wealth might be, it's ours as long as we didn't cheat anyone along the way. By and large, this belief has been enshrined in the laws of democratic countries, and we generally believe that it is morally sanctioned by the Christianity. It is not, as we can see from these truths in Scripture:
God intended the earth and everything in it for the sake of all human beings. Thus, created goods should flow fairly to all.
These principles are strong, so strong in fact that it is easy to believe that Jesus can't really be asking this of us. Indeed, if taken seriously, these principles would radically disrupt our lives and the social order. It would no longer be business as usual.
To take just one example: there are nearly forty-five million refugees in our world today, most of them looking to cross a border into a new country. Is it realistic for any country today, in biblical terms, "to welcome the stranger", to simply open its borders and welcome anyone who wants to cross? That's simply not realistic or socially expedient regarding what it would mean practically in terms of our comfort and security.
While that may be granted, what may not be granted is that our (seemingly) necessary social and political pragmatism in dealing with "the widow, the orphan, and the immigrant" may cloak itself with Jesus and the Bible. It may not. This is antithetical to Jesus. Whether or not this upsets our security and comfort, God is always on the underside of history, on the side of the poor.
