Abstract: We give conditions under which bounded solutions to semilinear elliptic equations $ \Delta u = f(u)$ on domains of $ \mathbb{R}^2$ are continuous despite a possible infinite singularity of $ f(u)$. The conditions do not require a minimization or variational stability property for the solutions. The results are used in a second paper to show regularity for a familiar class of equations.
