Feynman's method of functional integration is applied to meson-nucleon scattering. The scattering amplitude is obtained exactly in charged meson pair theory with neglect of nucleon recoil, and it is obtained in an approximation to linear charged meson theory with neglect of recoil. The results are the same as one obtains using the Chew-Low method.
