Good question Ravindran!
First let's look at what Jesus instructed, talking to His disciples (not some special priesthood or clergy), "do this in remembrance of me."
There is not any mention of who is to preform it or who can partake of it, ...and even Judas participated, Luke 22:14 it's too bad man has made so many rules and regulations concerning communion that keep people away.
As has been already mentioned the word fellowship is koinonia in the New Testament and the meaning is to have all things in common, with that in mind, I read in 1 John that John wants us to have this same koinonia with Jesus that the disciples had had with Him,
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; 1 John 1:1
John is telling us they heard, looked at, contemplated and touched Jesus and he wants us to be able to do the same thing, ...we hear Jesus through His Word, we see Him through the allegorical imagery He presents, we contemplate these Truths as how the are applicable in our lives, but how can we touch Jesus, ..at the Lord's Table, ...Jesus said,
Take, eat: this is my body, which is broken for you: this do in remembrance of me. 1 Cor 11:24
So mystically and symbolically we can believe we are following His commandment,
Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. John 6:53
(Please do not think I'm purporting or in agreement with the heresy of the RCC)
And,
This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. 1 Cor 11:25
If we add to that what Paul teaches us that many are weak, sick, and sleep because they have not given the communion the worth or reverence it merits, then we can see from this that there is a worth or reverence that we can give to communion that will heal our weakness, sickness, and prevent us from being taken home too soon (please remember I don't believe in the WoF teachings either, the enemy can not create so he will always try to deceive through imitation), ...so is Paul teaching us there is power in the communion service, ...looks like it, Isaiah tells us,
But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed. Isa 53:5
So in the taking of communion are we actually handling, touching Jesus, I think we could say yes, if you can accept it, in a mystical sense (just like in holding the photo of one that is no longer with us enables us to see and be with that person for a moment in time mystically), ...we read wounded for our transgressions, bruised for our iniquities, that was during His scourging, Paul tells us to judge ourselves, when we come to the Lord's Table, is there a sin hounding us, that has a hold on us, then judge that sin and ask the Lord to liberate us, by His stripes we are healed, we can receive cleansing and healing in our spirits (weak) at the Lord's Table, have we lost our peace, is our soul restless, anxious then we need to judge the reason why and repent and we will be healed emotionally (sick), at the Lord's Table and finally we can come to the Lord's Table and if it's His will be healed physically (sleep),
...in coming to the Lord's Table and giving it the worth, reverence or merit He deserves I prefer to use a loaf of bread, that way I when I tear off a chunk I remember it was because of my sin His body was wounded and bruised, for me it's a constant reminder of my position and state to that of my Lord and God, I break off a large piece to be able to slowly chew the bread 39 times, thus allowing the time for the Holy Spirit to search me and reveal to me my sin, to cleanse me, restore my peace and if He chooses to heal me physically at this time.
After the cleansing and restoration comes the joy, the drinking of His blood, a time of celebration of His New Covenant with mankind, though my sins were as scarlet I have been washed with the blood of the lamb and I'm as white as snow, a child of God, a prince in the Kingdom of God! Halleluiah!!!
That's how we look at communion, we eat at the Lord's Table in our home, whenever and as often as we want, ...personally, I'm such a sinner that the ten-fifteen seconds allotted to us in most church services is not enough time to give the worth and the reverence and to reflect on what He has done for me during their Communion service.
Blessings,
