We make an idol of truth itself, for truth without charity is not God, but his image and an idol which we must not love or worship; still less must we worship its opposite, which is falsehood.
It is false piety to preserve peace at the expense of truth; it is false zeal to preserve truth at the expense of charity.
(More thoughts from Blaise Pascal)

So how would you fit these truths from Pascal into practical living or ‘modern’ religion?
I don’t believe they fit ‘modern’ religion. There is a current in modern thinking that idolizes love but fosters hatred of anyone who does not buy the currently acceptable brand of love.
Doesn’t practical Christian living require spiritual and moral integrity? That is what I see in Pascal’s thoughts (pensées).
