In Belgium, organized secularism (French: Laïcité organisée, Dutch: georganiseerde vrijzinnigheid) is the local associations and organizations which provide moral support for naturalist, atheist, agnostic, secular humanist, freethinking, Bright, or irreligious and non-confessional citizens. A person who subscribes to such entities or ideologies, or at least espouses an interest in "free inquiry" apart from religious traditions is described as a "secular" or "free-thinker" (French: laïque, Dutch: vrijzinnig).
In Dutch-speaking Belgium, the leading humanist group is deMens.nu (Humanity Now, formerly known as the Union of Liberal Associations), which acts as a national federation for the non-religious and an umbrella group for local "liberal humanist" and freethought associations. In French-speaking Belgium it is the Centre d'Action Laïque (CAL, or Centre for Secular Action).
In contrast to the French model for communal organization for irreligionists and nontheists, the Belgian model is considerably more structured and tight-knit due to the Netherlands-like pillarization of Belgian religious systems and communities; in such a structure, various social organizations, such as scouting troops, trade unions and cooperatives and mutual societies are duplicated for each religious or philosophical community (Catholic, Protestant, Jewish, Muslim, socialist, liberal, etc.). Hence, many Belgian nontheists and secular humanists participate in congregation-style services led by secular pastors and chaplains. This parallels the distinction in the United States between secular humanists and religious humanists, who differ according to their view of humanism as an analytical term for their implicit beliefs or a distinct religion-like philosophy.
