There is no true peace without truth . There cannot be true peace if everyone is his own criterion, if everyone can always claim exclusively his own rights. without at the same time caring for the good of others .of everyone on the basis of the nature that unites every human being on this earth.
And when we are dealing with individuals in charity and in kindness and respect for the other person we should still propose that these morals are true for them even if they don't want to accept them. It is true for them and it is true for the good of humanity . Most of us don't realize just how badly our culture is affected by relativism the spiritual poverty .
To repeat those word from Pope Francis
" In an age sceptical of truth, we believe not only that truth exists but that it is found through faith in Jesus Christ the Incarnate Son of God. The Holy Spirit brings us to Jesus. he guides the whole church into the fullness of truth"
