  We give a complete representation of virtual Compton scattering $\gamma^* p
\to \gamma p$ at large initial photon virtuality $Q^2$ and small momentum
transfer squared $t$ in terms of the light-cone wavefunctions of the target
proton. We verify the identities between the skewed parton distributions
$H(x,\zeta,t)$ and $E(x,\zeta,t)$ which appear in deeply virtual Compton
scattering and the corresponding integrands of the Dirac and Pauli form factors
$F_1(t)$ and $F_2(t)$ and the gravitational form factors $A_{q}(t)$ and
$B_{q}(t)$ for each quark and anti-quark constituent. We illustrate the general
formalism for the case of deeply virtual Compton scattering on the quantum
fluctuations of a fermion in quantum electrodynamics at one loop.
