Letter to Pius IX. Bishop and Sovereign of Rome, Giacinto Achilli, a Minister of the Italian Catholic Church.

It is not unknown to you that I addressed two letters to your exalted predecessor, Gregory XVI., making a full retractation of the Romish doctrines which I had professed, more or less, up to 1841, and declaring to him my entire belief in Divine Scripture alone, to the exclusion of everything else. In this faith I intend to live and die, so help me God and His holy Word!

Being appointed, however, by the will of the Lord, a minister and elder in His Church, I cannot abstain from the exercise of that employment without entailing upon myself God's anger, and committing a culpable desertion of duty. My ministry is consecrated to the Church of Jesus Christ, and I am deeply impressed with the obligation of fulfilling my vocation. "The Pastor and Bishop of souls" gives me both the command and the strength to discharge my duties. The Church, which is the people, calls me to serve it. I must be faithful to my ministry, rendering a good account of the charge entrusted to me.

I have been bidden to keep in remembrance "that true faith which is in me," and "to keep alive that gift of God which is in me by the imposition of hands," seeing that God "has not given us a spirit of fear," but of strength, and of love, and of a sound mind. Therefore, "I must not be ashamed of the testimony of our Lord." "I know in whom I have believed, and I am persuaded that He is able to keep that which I have committed unto Him against that day." I therefore "keep the form of sound words which I have heard, in faith and love which is in Christ Jesus." "I keep that good thing, which was committed unto me by the Holy Ghost, which dwelleth in me." I profess before God and the Lord Jesus Christ "to preach the Word, to be instant in season and out of season, to reprove, rebuke, exhort with all long-suffering and doctrine." I purpose to be vigilant in everything, "to endure afflictions, to do the work of an evangelist, to make full proof of my ministry."

Such being my office, such my obligations, here I stand before you, Holy Father, "studying to show myself approved of God, a workman not needing to be ashamed, rightly dividing the Word of Truth." I know that the elders who have performed well the duty of ruling should be "reputed worthy of double honour; especially those who labour in the Word and in doctrine." You are the elder to whom was recently committed the charge of ruling over the Church of our country; and this charge was committed to you by other elders, who divide amongst them the various offices of that Church, or who are called to preside over other Churches. You the overseer, or bishop, of the Church of Rome, took upon you the heavy responsibility of feeding that portion of the flock of Christ, and of strengthening your brethren with good example and holy doctrine; your brethren, who look to you for counsel and direction, and depend in a certain degree on you, regarding you as an elder brother, whose judgment and prudence may aid their timidity and weakness. On you, therefore, it devolves to propose to them that which is of God and of the Lord Jesus Christ, and which tends to the welfare of His Church. You it behoves to restore the truths of religion to their primitive purity; to take away every extraneous admixture; to separate the good wheat from the tares, in order to give to the Christian people the nourishment of faith and of salvation. Your brethren look up to you in this matter, which ought to be conducted with harmony, in order to preserve the union of the Christian Churches: and although each possesses over his own Church an equal authority, they nevertheless hesitate to act without you; they expect you to set this work in motion, and to be their model in the reformation of doctrine.

Yes, Holy Father, the reformation of doctrine is the serious business to which you and your brethren are called by the people to turn your earnest attention; for it is well known to all Christians, that upon the purity and holiness of the doctrines of the Church depend the purity and holiness of the actions of believers. Now, the doctrines which proceed from man are neither pure nor holy; seeing that "God hath concluded them all in unbelief, that He might have mercy upon all." Therefore, none but the doctrines of God are the truth in religion; all others are lies.

Think you, then, that those are doctrines of God, which are not contained in His Book, but are opposed to the sacred precepts of His holy Word? Have you ever compared the doctrines taught in primitive times with those of later ages? Have you ever compared the dogmas of the Decretals with the doctrines of the Bible? I have compared them, and have shuddered in amazement, that so many strange novelties, amounting to an actual renunciation of the ancient faith, the pure creed of our fathers, should ever have been introduced into Christianity.

Strip yourself, then, of that fatal prepossession that your predecessors were holy and infallible. Examine carefully the sources of the existing belief. Observe what is from God, and what proceeds from man. Man has erred in presuming to legislate in the things of God. Not only singly, but in the aggregate, men have erred. The Divine assistance was no doubt promised, but it was for preserving the ancient doctrines, not for framing new ones; the Holy Spirit is with those who believe in the ancient Scriptures, but not with those who tamper with the Divine Word. In the middle ages the ministers of the Catholic Church revelled in innovation, and from that time the desire for change has grown upon them to such a degree, that primitive Christianity can no longer be recognised.

Think you that it was ever permitted to men to add their ideas and thoughts to the ideas and thoughts of God, or to take anything away from the Divine Book? Are you not rather persuaded with me that whosoever does this, on him are denounced the chastisements of God, as it is written in the last verse of the Divine Revelation—"God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book?" To add to the meaning, or to change it! to overturn, on certain points, the entire system and spirit of the Divine Legislator! I ask you, who were an elder before me, and a ruler among the elders, are such things to be endured? However ancient these errors may be, however concealed by some or acquiesced in by others, shall prescription prevail to this extent? No! not any antiquity can establish the abuses of religion; and even if the whole world were combined to maintain error (supposing such a thing were possible), even that would not hinder its destruction by any single person who had with him the Word of Truth.

This, then, is the point at issue;—the abuses of Rome have existed long, and obtained for a long time the support of the multitude; do they for that reason cease to be abuses? Her errors have been adopted, applauded, followed; do they on that account cease to be errors? And must not abuses and errors be reformed wheresoever they may be found, or however long they may have existed?
