Now, over the last few months, we've seen a number of challenges - certainly over the last six years. But part of what I want to touch on today is the degree to which we've seen professions of faith used both as an instrument of great good, but also twisted and misused in the name of evil.
As we speak, around the world, we see faith inspiring people to lift up one another - to feed the hungry and care for the poor, and comfort the afflicted and make peace where there is strife. We heard the good work that Sister has done in Philadelphia, and the incredible work that Dr Brantly and his colleagues have done. We see faith driving us to do right.
But we also see faith being twisted and distorted, used as a wedge - or, worse, sometimes used as a weapon. From a school in Pakistan to the streets of Paris, we have seen violence and terror perpetrated by those who profess to stand up for faith, their faith, professed to stand up for Islam, but, in fact, are betraying it. We see ISIL (the Islamic State), a brutal, vicious death cult that, in the name of religion, carries out unspeakable acts of barbarism.
We see sectarian war in Syria, the murder of Muslims and Christians in Nigeria, religious war in the Central African Republic, a rising tide of anti-Semitism and hate crimes in Europe, so often perpetrated in the name of religion.
So how do we, as people of faith, reconcile these realities - the profound good, the strength, the tenacity, the compassion and love that can flow from all of our faiths, operating alongside those who seek to hijack religious for their own murderous ends?
Humanity has been grappling with these questions throughout human history. And lest we get on our high horse and think this is unique to some other place, remember that during the Crusades and the Inquisition, people committed terrible deeds in the name of Christ. Michelle and I returned from India - an incredible, beautiful country, full of magnificent diversity - but a place where, in past years, religious faiths of all types have, on occasion, been targeted by other peoples of faith, simply due to their heritage and their beliefs - acts of intolerance that would have shocked Gandhiji, the person who helped to liberate that nation.
So this is not unique to one group or one religion. There is a tendency in us, a sinful tendency that can pervert and distort our faith. In today's world, when hate groups have their own Twitter accounts and bigotry can fester in hidden places in cyberspace, it can be even harder to counteract such intolerance. But God compels us to try. And in this mission, I believe there are a few principles that can guide us.
And, first, we should start with some basic humility. I believe that the starting point of faith is some doubt - not being so full of yourself and so confident that you are right and that God speaks only to us, and doesn't speak to others.
Our job is not to ask that God respond to our notion of truth - our job is to be true to Him, His word, and His commandments. And we should assume humbly that we're confused and don't always know what we're doing and we're stumbling towards Him, and have some humility in that process. And that means we have to speak up against those who would misuse His name to justify oppression, or violence, or hatred with that fierce certainty. No God condones terror. No grievance justifies the taking of innocent lives, or the oppression of those who are weaker.
And so, as people of faith, we are summoned to push back against those who try to distort our religion - any religion - for their own nihilistic ends. And here at home and around the world, we will constantly reaffirm that fundamental freedom - freedom of religion - the right to practice our faith how we choose, to change our faith if we choose, to practice no faith at all if we choose, and to do so free of persecution and fear and discrimination.
There's wisdom in our founders writing in those documents that help found this nation the notion of freedom of religion, because they understood the need for humility. They also understood the need to uphold freedom of speech, that there was a connection between freedom of speech and freedom of religion. For to infringe on one right under the pretext of protecting another is a betrayal of both.
But part of humility is also recognising in modern, complicated, diverse societies, the functioning of these rights, the concern for the protection of these rights calls for each of us to exercise civility and restraint and judgement. And if, in fact, we defend the legal right of a person to insult another's religion, we're equally obligated to use our free speech to condemn such insults and stand shoulder-to-shoulder with religious communities. Just because you have the right to say something doesn't mean the rest of us shouldn't question those who would insult others in the name of free speech. Because we know that our nations are stronger when people of all faiths feel that they are welcome, that they, too, are full and equal members of our countries.
So humility, I think, is needed. And the second thing we need is to uphold the distinction between our faith and our governments. The United States is one of the most religious countries in the world. And one of the reasons is that our founders wisely embraced the separation of church and state. Our government does not sponsor a religion, nor does it pressure anyone to practice a particular faith, or any faith at all. And the result is a culture where people of all backgrounds and beliefs can freely and proudly worship, without fear. It's from the heart.
It's not the case in authoritarian governments that elevate an individual leader or a political party above the people, or, in some cases, above the concept of God Himself. So the freedom of religion is a value we will continue to protect here at home and stand up for around the world.
