"Whatsoever you bind on earth shall be bound in heaven....."
This is to those walking in obedience and faith to the Lord Jesus Christ- it is permission to make declarations and expect them to come to pass.

Most commentators don't read it that way. 

In Such Cases the Church Acts on God's Authority (18:18)
God authorizes the Christian judicial assembly that follows these procedures to act on the authority of heaven. The unrepentant person has already left God's way and cannot be restored without repentance. The verb tenses allow (though do not demand) the meaning the context suggests: the earthly action follows the heavenly decree (compare Mantey 1973). By removing an unrepentant sinner from the Christian community, believers merely ratify the heavenly court's decree (see Keener 1991a:141-43; in Jewish courts, compare t. Rossashana 1:18), removing branches already dead on the vine (compare Jn 15:2, 6).
[i]Bind and loose refer to the judicial authority of gathered Christians to decide cases on the basis of God's law. Most scholars thus recognize that this passage applies to church discipline (Cullmann 1953:204-5; R. Fuller 1971:141). [/i]

Others read it as giving the church the power to decide matters concerning faith and morality on behalf of god:

(1) Whatever you (in the church) declare to be unlawful on the one hand, or permissible on the other (see note on Matthew 16:19), will be held to be so in the sight of God; your judgment in regard to complaints brought before the church is accordingly ratified by divine warrant. (2) If two of you agree as to anything that is to be asked in prayer, it will be given you by God; when, therefore, your hearts are thus united in prayer, you are assured of the divine help and illumination, in order that, in every case, you may arrive at and, in the church, give effect to decisions in accordance with the mind of God.

Meyer's NT Commentary

The Catholic's use it to justify the passage of power from Peter to Paul and on down the line. http://www.catholic.com/quickquestions/w...atthew-181

And then there are those who think it's about casting out demons:

The more popular use of "binding" today in many circles (exercising authority over the devil) resembles instead an ancient practice in the magical papyri-also called "binding" (see note on 12:29)-of manipulating demons to carry out a magician's will. (The Bible does support Christians' authority to cast out real demons-compare comment on 17:17-but the only "devils" in this passage are fully human ones, and they are being cast out of the church!)
