An abstract of a commentarie by Dr. Martyn Luther, u[pon] the Galathians. Wherein the difference betweene the law, the gospell, and the strength of faith is declared. Whereunto is added divine and morall Latine sentences, taken out of the fathers, and other authors, which are cited i[n the] margent of the Practise of piety, but not E[ng]lished there; which for their excellency, and benefit of those who understand not Latine, are here translated.
