  We present a Lorentz gauge theory of gravity in which the metric is not
dynamical. Spherically symmetric weak field solutions are studied. We show that
this solution contains the Schwarzschild spacetime at least to the first order
of perturbation. Next, we present a special case of the theory. It is shown
that the Schwarzschild metric is now an exact solution. Moreover, we show that
the de Sitter space is an exact vacuum solution and as a result the theory is
able to explain the expansion of the universe with no need for a dark energy.
Within this special case, quantization of the theory is also studied. The basic
Feynman diagrams are derived and renormalizability of the theory is studied
using the power-counting method. We show that under a certain condition the
theory is power-counting renormalizable.
