“. . . the reason I was born and came into the world is to testify to the truth. Everyone on the side of truth listens to me.”
To which Pilate replies,
“What is truth?”
As we think about a theology for an Age of Limits I suggest that one of the bases should be, “Understand and tell the truth”. The key word in that phrase is “understand”. Christians know that they must never lie. They also know that they must always speak and act with integrity.
Let your yea be yea; and your nay, nay
Telling the truth can go even further. In his book De Mendacio (On Lying), written around the year 395 CE, Augustine of Hippo says that it is wrong even to tell a white lie.
However, in our extraordinarily complex society it is often very difficult and challenging to determine exactly what is truth. Consider, for example, the effect of the current pandemic on greenhouse gas (GHG) emissions. Environmentalists are encouraged that, in spite of the all the problems and tragedies that it has caused, the consequent reduction in economic activity has at least led to an improvement in air and water quality, and also in GHG emissions.
However, it turns out that the climate change benefits of the wrenching changes we are enduring have not been all that great. Greenhouse gas emissions are down by only 5% this year. How can that be? How can the enormous cutbacks and losses that we have endured led to such a small decrease in emissions?
To find an answer, let’s look at which sectors of the economy use fossil fuels. In round numbers they are:
- Utilities — 45%
- Industry — 25%
- Transport — 20%
- Residential — 5%
- Other (including agriculture) — 5%
The picture below shows grounded jets at Dallas-Fort Worth airport. The transportation industry has gone through wrenching cutbacks. Indeed, the tourist industry has pretty well collapsed. But, as the highlighted number shows, that industry accounts for only 20% of GHG emissions, which is why the fall in overall emissions is less than most people would have expected.
A 5% cutback reduction in GHG emissions is good, but the cost has been enormous. Not only have tens of thousands of people died in the United States alone, there have been drastic reductions in the number of elective medical procedures, the consequences of which are not yet known. And more than 30 million people have lost their jobs in just two months. Environmentalists like to use the word “sustainable”. Well, what we have gone through in the last two months is unsustainable.
Yet the United Nations tells us that, if we are to stabilize the earth’s temperature, we need to reduce greenhouse gas emissions by 7.6% per year, every year for the next twenty years. The reductions that we have seen this year have been insufficient to meet the U.N. goals in spite of the enormous human and economic cost. Yet, if we are to achieve the U.N. targets, we need to repeat what has happened this year every year for the next twenty years. That does not mean that we stabilize at current levels of economic activity and unemployment — it means that we repeat what we did this year every year for the next twenty years.
I started this post by posing Pilate’s question, “What is truth?” I suggest that, if the church is to provide the leadership that is so badly needed then people in the faith community need to understand complexities of the type just described. This will be difficult. Most church leaders have a liberal arts background, and have had little training in science, technology or mathematics. Hence, they do not gravitate to the type of analysis just provided. In particular, they rely on qualitative statements and goals. For example, the Episcopal church has published a mission statement to do with climate change. It reads in part,
Our General Convention policy calls on lawmakers to significantly reduce carbon emissions within this century
What is the meaning of the word “significant” in the above statement? We need to apply a number to that word. If the number we select is an annual reduction of 7.6% in GHG emissions per annum, then the mission statement needs to address the drastic economic and human changes that are implied. This is not to say that we should not strive to meet that goal, but it does mean that we understand the quantitative nature of truth.
