There is, perhaps, nothing more remarkable, when you study the life of the Church at large and of each congregation individually, than the little interest which its members take in each other. In most cases the entire concern of the membership devolves on a few, or perhaps on the pastor alone; in many instances the amount of interest and sympathy which is shown to each other extends only to a formal, a very cool, social recognition; in some there is not even the interest which secures that. People go in and out of the same church-building, month after month, year after year, without as much as knowing, or caring to know the name of their fellow-member or worshiper. When difficulties arise and embarrassments, those who belong to the Christian Church feel no more liberty to call on a member of the Church for counsel or aid than they would on any other person; when disheartened and discouraged, in need of sympathy and a kind word, they have no reason to suppose that a single member of the Church sympathizes with them. And when living in the neglect of Christian duty, none of the members ever stop to administer an admonition or gentle rebuke to keep the backslider from a melancholy fall. In a word, people are left to take care of themselves very much alone; and this is the more remarkable when you consider the condition of those who largely make up the membership of a congregation like ours. Many of them are young and inexperienced in Christian life, gained from families where there is no religion, no kindred to help them on to God, rather, where they are exposed to influences that would draw them aside, and where every effort ought to be made to keep them in the fold. The reflections, my beloved, and the constant cry, "What is the Church doing for its members? See how other organizations are helping each other, how they care for their constituents," have led me to propose for our consideration this morning: _What are the duties which the members of the Church owe to each other?_ We shall inquire _I. What the Christian Church is_, _II. note a few traits which ought to distinguish its members_. May God's Spirit make the sermon a profitable one.
