I found a bunch of references to "Gospel of Liberty".... interesting...
"...brethren who have laid down their lives in the ministry, while making their best effort to proclaim the Gospel of liberty and of life and salvation to the inhabitants of the world." (President Joseph F. Smith. CR April 1910.)

"God loves the whole world; he gave his Son to save it; he is using America and her allies as instruments for the spread of the Gospel of Liberty, and in their wake, after they have cleared the way, will follow the missionaries of the Lord Jesus Christ. Amen." (Elder Orson F. Whitney. CR April 1918.)

I think the time is not far distant when the light that shines from the lives of the faithful Latter-day Saints will draw many of the honest in heart into the straight and narrow path. This is the gospel of liberty, restored through the Prophet Joseph Smith. (Elder German E. Ellsworth. CR April 1907.)

"The gospel that we have received is a gospel of liberty but not of license. There is nobody in bondage in this church. We are at perfect liberty to do that which we desire to do, so far as we have power. But we are not permitted, if we are saints of the living God, to go into corruption and wickedness and into the evils of this world. True, we have the power, but the Lord has given us commandments concerning these things, and He expects us to be a righteous people." (Elder Charles W. Penrose CR October 1904.)

"We are to advocate the freedom of conscience, and the freedom of speech and of good law. The freedom of speech should not be extended to license, whether it be by word of mouth or by the press, but that liberty which God designs for his children to have is embodied in the Gospel of Jesus Christ, so that our gospel is a gospel of liberty." (President Charles W. Penrose. CR October 1918.)

"We are all searching for happiness; we hope for it, we think we live for it, it is our aim in this life. But do we live so as to enjoy the happiness we so much desire? There is only one way for Latter-day Saints to be happy, which is simply to live their religion, or in other words believe the Gospel of Jesus Christ in every part, obeying the gospel of liberty with full purpose of heart, which sets us free indeed. If we will, as a community, obey the law of God, and comply with the ordinances of salvation, then we may expect to find the happiness we so much desire, but if we do not pursue this course we cannot enjoy the unalloyed happiness which is to be found in the Gospel. To profess to be a Saint, and not enjoy the spirit of it, tries every fiber of the heart, and is one of the most painful experiences that man can suffer." (Brigham Young. 12:168. Discourses of Brigham Young.)

"In the light of the labor and continuing work of the Lord among the disembodied spirits, Peter, James, and the other disciples of Christ, in the intervening centuries from the meridian of time to the present, have been busily engaged in their callings and are proclaiming the gospel of liberty and truth to the captives in prison in the spirit world. There can be no doubt that the Prophet Joseph Smith, his brother Hyrum, Brigham Young, Heber C. Kimball, Willard Richards, Wilford Woodruff, and many of the servants of God upon the earth in their own day and time, have, since their departure, ministered unto the spirits in the intermediate period of time between death and resurrection." (Elder Alvin R Dyer. Who Am I? The Space Between Death and Resurrection)

""Mormonism" is the Gospel of liberty, for it opens the door of freedom, and throws off the fetters of bondage. I bear my testimony to the truth of the Gospel of Jesus Christ as revealed by the Prophet Joseph Smith, and to the correctness of the organization of the Church of Jesus Christ of Latter-day Saints; also to the revelations given through the prophets of God both ancient and modern. " (Elder Ezra Taft Benson. Member of the Council of Twelve from July 16, 1846, to September 3, 1869. "Testimonies of the Divinity of the Church 1830 - 1930 (S. Bennion)")

"Ever since the beginning of human existence on earth, the deposed son of the morning and his followers have been compassing the captivity of souls. The plan of salvation is the gospel of liberty. And now, in these the last days, immediately precedent to the return of Christ, who shall come to rule in righteousness on earth, the arch-fiend is making desperate effort to enthrall mankind under the autocracy of hell. The conflict under which the earth has been made to groan was a repetition of the premundane war, whereby the free agency of spirits was vindicated; and the eventual issue of the later struggle was equally assured." ( Vitality of Mormonism. James E. Talmage)
