A linear potential model for heavy quark systems is constructed from canonical quantum field theory. This is done on the basis of explicit and well-defined assumptions. The assumptions are motivated by lattice formulations of gauge theory, but are formulated in a continuum framework. Thus, at the very least, we present a precise set of requirements sufficient for the existence of a linear confining model. In addition, a program for going beyond the potential-model approximation is discussed. This involves both relativistic corrections and consideration of the role of excitations in the gauge field configuration.
