He also wrote, while resident in Portsmouth, a series of letters addressed to the Rev. Joseph Buckminster, upon important doctrinal subjects, which was published in one volume. A Controversy with Rev. Mr. Walton was written and published here, besides one or two minor works, including a school catechism, for a long period of years in general use among the denomination. In addition to the labor necessary to produce these in connection with his regular professional duties, he was also associate editor of a religious quarterly, entitled the "Gospel Visitant," in which, however, he had no further interest than his editorial connection. His contributions to this work were copious, and marked by the same profound reasoning capacity and lucid style that have characterized every work he has produced. It was while engaged in editing this publication that he came to the full belief that there was no punishment after death, and ever after, he preached the doctrine of universal salvation in this spirit, and labored strenuously in its defence and support. Relative to this subject Mr. Ballou has written:--"I cannot say that I was fully satisfied that the Bible taught no punishment after death, until I obtained this satisfaction by attending to the subject with Bro. Edward Turner, respecting the doctrine of the Scriptures upon this question. We agreed to do the best we could, he in favor of future punishment, and I on the contrary. Our investigations were published in a periodical called the 'Gospel Visitant.' While attending to this correspondence, I became entirely satisfied that the Scriptures begin and end the history of sin in flesh and blood, and that beyond this mortal existence the Bible teaches us no other sentient state but that which is called by the blessed name of life and immortality." In another article relative to the same subject he says:--"The doctrine of punishment after death has, by many able writers, been contended for; some of whom have argued such punishment to be endless, and others limited. But it appears to me that they have taken wrong ground who have endeavored to support the latter, as well as those who have labored to prove the former. They have both put great dependence upon certain figurative and parabolical expressions, or passages of Scripture, which they _explain_ so as to cause them to allude to such an event. It appears to me that they have not sufficiently attended to the nature of sin, so as to learn its punishment to be produced from a law of _necessity_, and not a law of _penalty_. Had they seen this, they would also have seen that a perpetuity of punishment must be connected with an equal continuance of sin, on the same principle that an effect is dependent upon its cause." This brief paragraph will show the reader how Mr. Ballou was accustomed to argue upon this subject, of such vital importance to all, and which is a question still in the minds of many of our Universalist brethren, both ministry and laity.
