In July, 1844, I wrote to a friend: "I am far more certain, according to the fathers, that we _are_ in a state of culpable separation than that developments do _not_ exist under the Gospel, and that the Roman developments are not the true ones." I then saw that the principle of development was discernible from the first years of the Catholic teaching up to the present day. I came to the conclusion that there was no medium, in true philosophy, between atheism and Catholicity, and that a perfectly consistent mind must embrace either the one or the other. I saw that no valid reasons could be assigned for continuing in the Anglican Church, and that no Valid objections could be taken to joining the Roman. In February, 1843, I had made a formal retraction of all the hard things which I had said against the Church of Rome, and in September I had resigned the living of St. Mary's, Littlemore included. I began my "Essay on the Development of Doctrine" in the beginning of 1845, and was hard at it till October. Before I got to the end, I resolved to be received into the Catholic Church. Father Dominic came to Littlemore on October 8, and did for me this charitable service. I left Oxford for good on February 23, 1846. _IV.--THE FAITH OF A CATHOLIC_ From the time that I became a Catholic of course I have no further history of my religious opinions to narrate. I do not mean that I have given up thinking on theological subjects, but that I have had no variations to record, and have had no anxiety of heart whatever. I have been in perfect peace; I never have had one doubt. Nor had I any trouble about receiving those additional articles which are not found in the Anglican creed. I am far from denying that every article of the Christian creed is beset with difficulties, and it is simple fact that I cannot answer those difficulties. But ten thousand difficulties do not make one doubt. Of all points of faith, the being of a God is encompassed with most difficulty, and yet borne in upon our minds with most power.
