According to SDA can all pastors forgive sin, or just the original twelve apostles?

I have a question relating to Matthew 18:18. I want to specifically ask the Seventh-day Adventist church about this. It says: > "I can assure you that when you speak judgment here on earth, it will > be God's judgment. And when you promise forgiveness here on earth, it > will be God's forgiveness." Matthew 18:18 ERV Does this verse apply only to the twelve apostles that Jesus spoke at that time, or does it also apply to all pastors and ministers, that they can forgive sin, and/or does it also apply to churches today that whoever they "loose" from their churches would be "loosed" from heaven? So if a church today (let's suppose it's the one true church) excommunicate a member does that mean that that person is excommunicated in heaven? Does Seventh-day Adventism vary from mainstream Christianity on this topic?
