Article 28: The Obligations of Church Members
“We believe that since this holy assembly and congregation is the gathering of those who are saved and there is no salvation apart from it, no one ought to withdraw from it, content to be by himself, regardless of his status or condition.
But all people are obliged to join and unite with it, keeping the unity of the church by submitting to its instruction and discipline, by bending their necks under the yoke of Jesus Christ, and by serving to build up one another, according to the gifts God has given them as members of each other in the same body.
And to preserve this unity more effectively, it is the duty of all believers, according to God’s Word, to separate themselves from those who do not belong to the church, in order to join the assembly wherever God has established it, even if civil authorities and royal decrees forbid and death and physical punishment result.
And so, all who withdraw from the church or do not join it act contrary to God’s ordinance.” Belgic Confession. Author, Guido de Bres, martyred for the faith.
So the question is, how seriously do you take Christ’s body, the church? As R.C. Sproul noted once, “If you have no time for the body of Christ, Christ has no time for you.”
