A consistent variational derivation of the Majorana 4-spinor field equations
    coupled to Einstein’s theory of gravitation is given. The equivalence of the
    first and the second order variational field equations is explicitly
    demonstrated. The Lagrange multiplier 2-forms we use turn out to be precisely
    the Belinfante-Rosenfeld 2-forms that are needed to symmetrize the canonical
    energy-momentum tensor of the Majorana spinor.
