Paul does not settle the issue of whether these rules and customs are to be upheld. What he says is that we are to leave others to their practices and not pass judgement on them. He writes: "Who are you to pass judgement on the servant of another? It is before his own master that he stands or falls. And he will be upheld, for the Master is able to make him stand."
Do not read into this that "anything goes." Rather, gather from Paul that each will be accountable for their own actions; each will need to be judged by God as to their dedication and devotion. It is a difficult thing - to not judge.
In a few short days you will be leaving campus. As you journey to parts far and wide, you will encounter Christians and Christian communities whose customs and habits may be different from what you have experienced here. You may prefer their way of doing things; or you might critique them based on what you have come to find familiar here. Remember Paul's words. Know that it is our devotion to Christ which God judges and not the particular ways in which we show that devotion. Ways and customs differ; it is the same Lord who is worshiped and glorified.
Things will be different at LCM when those of you who are returning do so. The construction of a new narthex means we will worship in the Fellowship Hall - probably hosting three services on Sunday morning. Will the new schedule be more pleasing, or disruptive? We will have to wait and seen.
Do not judge; and do not fear the judgement of others. Be the servant of God whom you have come to know yourself to be. Stand firm in your devotion to Him, and know that you are good and acceptable and deeply loved.
I will be back with you in August - have a wonderful summer.
