"And whether one member suffer, all the members suffer with it; or one member be honored, all the members rejoice with it" (I Corinthians 12:26). The latter part of this verse speaks of when a brethren in the body of Christ rejoices, you are to rejoice with him. Take for example a wedding, baby shower, tribute to a minister or even a graduation. My questions are these: If I am able to attend but do not, have I sinned? Will this keep me out of heaven? I have contributed financially, mailed cards and texted well wishes. Do I have to be present to rejoice or morn or suffer with the brethren?
You are reading more into this verse than is there. This is about seeing what happens to your brethren as being an extension of yourself. So when members get married, you rejoice in their happiness, but that doesn't mean you are required to attend the wedding. When a member dies, you are saddened by the family's loss, but that doesn't mean you have to attend the funeral. What is being emphasized is the attitude and the feeling of camaraderie.
