Dear Nathan, Yes that article is nowhere to be found on the net. It’s in the Presbyterian Banner vol. 91 June 1904-05 edition…and those are getting harder to find. There is an entire set in Pittsburgh but they have it under lock and key! You can find my contact info at graceingibsonia.org. If you want the article send me an email and I’ll scan a copy for you.
Blessings,
Jeff

And by second essay I mean “Christian unity and Church Union…”

in an essay by Charles Hodge entitled “Is the Church of Rome a Part of the Visible Church?,” he states:

“…By a definition we do not mean a description including a specification of attributes which properly pertain to the thing defined; but an enumeration of its essential attributes and of none other.
…We may say that a church is a society in which the pure word of God is preached, the sacraments duly administered, and discipline properly exercised by legitimate officers. This, however, is a description of a pure and orderly church, and not an enumeration of the essential attributes of such a body. If we use that description as a definition, we must exclude all but orthodox Presbyterians from the pale of the church.
…This distinction between a description and definition, between an enumeration of what belongs to a pure church, and what is necessary to the being of a church, is often disregarded.
…the church consists of all those throughout the world who profess the true religion, together with their children. This is a legitimate established meaning of the term. In this view of the church, nothing is essential to it but the profession of the true religion.
…[particularly, a church is] an organized society professing the true religion, united for the purpose of worship and discipline, and subject to the same form of government and to some common tribunal.
…By the true religion cannot be meant all the doctrines of the true religion, and nothing more or less. For then no human society would be a church unless perfect both in knowledge and faith. Nor can it mean all the clearly revealed and important doctrines of the Bible for then no man could be a Christian and no body of men a church, which rejects or is ignorant of those doctrines. But it must mean the essential doctrines of the gospel, those doctrines without which no man can be saved.”

This same view is also articulated by James Bannerman in his book “The Church Of Christ” (1869) See chapter 5, on the ‘Notes’ Of The Church, where he states:

“First, there is an important distinction between what is necessary to the being of a Church, and what is necessary to its wellbeing… there is a distinction not less important to be borne in mind, in connection with this matter, between the things for which the Church was instituted, and the things that have been instituted for the Church.
…to hold to and preach the true faith or doctrine of Chirst [ie., the gospel] is the only sure and infallible note or mark of a Christian Church… other
things, such as sacraments and ordinances, the ministry, and the outward administration of the Church, are not essential to it, but only accidental.”

Thank you again, Cris. Archive.org is such a wonderful resource! Sorry for misspelling your name, above. I didn’t catch the autocorrect in my haste.

Thank you very much, Jeff and Chris!
