“I believe in one Holy, Catholic, and Apostolic Church.” Do you believe that all Orthodox Christians are members of one and the same body, and that therefore we must all “keep the unity of the Spirit in the bond of peace,” must care for one
another, help one another?
Do you believe that the saints are likewise members of the one body of Christ - that is, of the Church, and are our brethren, interceding for us before God in heaven? Do you respect every Christian, as a member of Christ, as His brother according to human nature? Do you love everybody as yourself, as your own flesh and blood? Do you generously forgive offences?
Do you help others in need, if you yourself have means? Do you teach the ignorant? Do you turn the sinner from the error of his ways? Do you comfort those who are in affliction? Faith in the Holy, Catholic, and Apostolic Church inspires, obliges you to do all this; and for all this you are promised a great reward from the Head of the Church - our Lord Jesus Christ.
