André Frossard asked one day to John Paul II what was the single most important saying he would leave to humanity if he was permitted to leave only one. Frossard expected the Pope would take a moment to think, but the answer came immediately: Truth will set you free.

All the Bible and all Christianity are contained in this short sentence expressing God’s plan for us: to set us free from evil so that we can welcome the Kingdom of God – that is, God himself – in our lives.

Nothing less than the one and whole Truth, who is a Person, can set us free. Nothing else than the love of truth can guide us on the way and ultimately bring us to the love of the One who said: I am the truth.

But there are obstacles:

It will happen with every sort of wicked deception of those who are heading toward destruction because they have refused to love the truth that would allow them to be saved. (2 Thess. 2:10)

whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son.
This is the verdict:
Light has come into the world,
but men loved darkness instead of light
because their deeds were evil.
All those who do evil hate the light,
and will not come into the light
for fear that their deeds will be exposed.
But those who live by the truth come into the light,
so that it may be seen plainly that what they have done
has been done in the sight of God
. (John 3:18-21)

The obstacles are on our part if intellect is not impaired and knowledge is sufficient. They are not metaphysical, but existential and moral, because the will can decide to go at something only seemingly good, or not good but desired, and which seems excusable or mitigated in the circumstance. The person imagines he is using his free will and doing what is right, but on the contrary, the will is enslaved by passion, sentiments, illusions or lies not submitted to rational enquiry or spiritual counsel.

The two Bible quotes above illustrate what happens when one prefers to believe and act on the false arguments provided by secular culture. This necessitates to bury the promptings of conscience under the outcry of the world against sound religion and sound thinking.

Secular advocates of evil like to think of themselves as humanists. They don’t believe their so-called humanism has amply been proven wanting, and dangerous. They just stick to their stubborn self-willed downfall, impervious to any warning.

As Jacques Maritain affirmed in 1936 in his book Integral Humanism, only Christian humanism is able to make the world more convivial, as it did in Byzantium and Medieval Europe. Whatever the causes for decadence in the last centuries, to pretend they are inherent to Christianity is to be ignorant of history. Civilization in traditionally Christian countries is obviously regressing parallel to the abandonment of Christian faith and sound morality under the lure of secular humanism, or because of persecution by secular powers hopelessly nearsighted, and often evil.
