Yes. Liberalism refers to a political ideology, that bigger government is better, that government should do more. Secularism is a belief that there is no God.
There is significant overlap between the two, though there are secular conservatives and religious liberals.
For liberal secularists, government becomes god, what we all should obey, the source of all rights and good, without limits or boundaries. That leads to totalitarianism.
Because the religious have another higher source of morality, barring Islam's unique demand for an Islamic theocratic source that marries religion with government, the religious Christians, Jews, Hindus, Buddhists tend to limit secular government's power.
