Oath-Sincerity of one's actions

The best way I could think of to analyze the word oath was to hit up dictionary.com. This definition struck me as important to sorority/fraternity life...
Oath: a solemn attestation of the truth of one's words or the sincerity of one's actions
The part that really speaks to me is the sincerity of one's actions. Yes, by joining a sorority or fraternity there are lots of things you are obligated to do such as community service, philanthropy, academic excellence, but I think we need to reflect on our intentions. Are we doing these things because they are required of us or because we want to be better individuals? Do we do community service because we want recognition or because we actually care about people other than ourselves? Oath seems to be a simple word meaning "promise", but it is much more complex than that. Oath is not only fulfilling our promises to our organizations but doing them in a manner that is sincere and meaningful because if we don't we are breaking our oaths. Another important aspect of oath, is that it unites all Greek organizations and sets us apart from other organizations. Furthermore, an oath is for life. When taking my oath, I don't think I realized the implications of that. This means that once you are an alum, you still hold an obligation to your organization. Your continued support is needed to further the growth of new generations, whether that be through donating to scholarship funds or volunteering with current members.
