Ideology is an idea about how the human world operates. By its nature, it is directed towards this world. Communism, liberalism, nazism, conservative, progressive and liberal are all ideologies - some better, much better, that others. But the Catholic Faith is not an ideology - Catholics may have hopes for this world, they might even be arch ideologues - but the Faith entrusted to St. Peter promises triumph over death, not an increase in the GDP or a global order.
