Yes the constitution doesn't support any one religion, but that merely means it isn't a theocracy, which is not the same as secular. The preamble states the that the governments right to rule comes from God, article 44 says God is due homage, most rights are subject to "public morality", all of which is hardly secular. The articles on abortion, blasphemy and a woman's place being in the home are all heavily influenced by Catholic teaching.
