Troublesome people.
A church member who is unrepentant,resistant to biblical principles and guidance by elders and continuing to sin, is not considered a troublesome person but a brother or sister in dire crisis. If they chose to continue to sin, then the church elders are biblically mandated to discipline that member. The end of that process calls for disaffiliation or revocation of membership in the church.
However, this does not mean that intercessory prayer is not offered for that individual or that they are not welcome to return once they have forsaken the sin and repented.
Discipline, accountability, sacrifice, responsibility and discernment and judgment are not bad concepts. Nor are they unchristian.
