The 1983 Code of Canon Law tells us that the Curia is composed of those institutes and persons who assist the Ordinary in governing the entire Ordinariate, especially in directing pastoral action, in providing for the administration of the Ordinariate, and in exercising judicial power.
The appointment of those who fulfil an office in the Ordinariate Curia belongs to the Ordinary. All who are admitted to an office in the curia must promise to fulfil their office faithfully, as determined by law or by the Ordinary, and observe secrecy within limits and according to the manner determined by law of by the Ordinary.
The Curia comprises the Vicar General, the Episcopal Vicar(s) where appropriate, the Chancellor, the Vice-Chancellor where appropriate, and the Financial Administrator.
