I did not intend to enumerate all the details involved in church discipline, or to portray Reformed churches as heartless towards members who fall out of their profession. By the way, I was quite glad to hear this morning that the consitory of my church decided not to excommunicate a member as they were supposed to on this date, the reason being that the person involved was actually taking the discipline of the church seriously, but had felt little concern and love from the other members. Consequently, I guess that our lack of care as a congregation prevented us from proceeding so quickly with the excommunication, and that the "protocol" is not always followed to the letter, depending on circumstances.
As for Mat. 16:19, Pastor Kok, I don't think it is referring to excommunication. I think the interpretation of John Gill makes a lot more sense.
