Ideological bias

Is there need to stress the possible ambiguity of every social ideology? Sometimes it leads political or social activity to be simply the application of an abstract, purely theoretical idea; at other times it is thought which becomes a mere instrument at the service of activity as a simple means of a strategy. In both cases is it not man that risks finding himself alienated? The Christian faith is above and is sometimes opposed to the ideologies, in that it recognizes God, who is transcendent and the Creator, and who, through all the levels of creation, calls on man as endowed with responsibility and freedom.
There would also be the danger of giving adherence to an ideology which does not rest on a true and organic doctrine, to take refuge in it as a final and sufficient explanation of everything, and thus to build a new idol, accepting, at times without being aware of doing so, its totalitarian and coercive character. And people imagine they find in it a justification for their activity, even violent activity, and an adequate response to a generous desire to serve. The desire remains but it allows itself to be consumed by an ideology which, even if it suggests certain paths to man's liberation, ends up by making him a slave. (Papal Writings, 14 May 1971).
