We study the asymptotics of a parabolically scaled, continuous and space-time stationary in time version of the well- known Funaki-Spohn model in Statistical Physics. After a change of unknowns requiring the existence of a space-time stationary eternal solution of a stochastically perturbed heat equation, the problem transforms to the qualitative homogenization of a uniformly elliptic, space-time stationary, divergence form, nonlinear partial differential equation. An important step is the construction of correctors with the appropriate behavior at infinity.
