Or, do you have to be a member of the church to take communion?
A Biblical church should not require a person be a member of their congregation to take Communion. However, the pastor should strongly advise all that they should be Christians to partake.
Here is what the Westminster Confession Of Faith says about Communion:
Chapter XXIX Of The Lord's Supper, Paragraph 8
Although ignorant and wicked men receive the outward elements in this sacrament; yet, they receive not the thing signified thereby; but, by their unworthy coming thereunto, are guilty of the body and blood of the Lord, to their own damnation. Wherefore, all ignorant and ungodly persons, as they are unfit to enjoy communion with Him, so are they unworthy of the Lords table; and cannot, without great sin against Christ, while they remain such, partake of these holy mysteries,a or be admitted thereunto.b
a. 1 Cor. 11:2729; 2 Cor. 6:1416.
b. 1 Cor. 5:67, 13; 2 Thess. 3:6, 1415; Matt. 7:6.
H/W is Hodge's commentary on this paragraph:
These sections teach the Reformed doctrine as to the relation which in the Lords Supper subsists between the sign and the grace signified; that is, as to the nature of the presence of Christ in the sacrament, and the sense in which, consequently, the worthy recipient is said to feed upon the body and blood of the Lord. This Reformed doctrine may be stated as follows
1. The bread and winealways remaining mere bread and wine, without changerepresent, by the divine appointment, the flesh and blood of the Redeemer offered as a sacrifice for sin. The relation between the bread and wine and the body and blood is purely moral or representative.
2. The body and blood are present, therefore, only virtually; that is, the virtues and effects of the sacrifice of the body of the Redeemer on the cross are made present and are actually conveyed in the sacrament to the worthy receiver by the power of the Holy Ghost, who uses the sacrament as his instrument according to his sovereign will.
3. When it is said, therefore, that believers receive and feed upon the body and blood of Christ, it is meant that they receive, not by the mouth, but through faith, the benefits secured by Christs sacrificial death upon the crossthat this feeding upon Christ is purely spiritual, accomplished through the free and sovereign agency of the Holy Ghost and through the instrumentality and in the exercise of faith alone; so that in no case is it ever done by the unbeliever. The unbeliever, therefore, receiving the outward sign with his mouth while he fails to receive the inward grace In his soul, only increases his own condemnation and hardens his own heart by the exercise. All, therefore, who are known to be unbelievers, and whose unbelief is made manifest either by their ignorance or their ungodliness, should be prevented, both for their own sake and for the Church sake, from coming to the Lords table until they are able to make a credible profession of their faith.
4. Hence, also, it follows that believers do, in the same sense, receive and feed upon the body and blood of Christ at other times without the use of the sacrament, and in the use of other means of grace.
