Hello AneirinJesus said that taking the emblems was for those in the New Covenant - destined to rule with him in heaven. So the beneficiaries of the New Covenant should not take the emblems.
Therefore if your calling is to live in heaven then you should take the emblems.
If, however you want to live forever in paradise on earth then you should not take the emblems.
Listen to God and Live Forever
What Does the Bible Really Teach?

Are the emblems the unleaven bread that is represented as Jesus's body in the Lord's Supper?
If so, do those that participate in the memorial, or believe in the significance of the memorial for that matter, also partake of the wine or as some suggest, grape juice being the fruit of the vine? Wouldn't partaking, eating (drinking) of the wine, which symbolizes Jesus' blood be contrary to a cornerstone witness belief that blood should not be eaten (drinking) if blood transfusions also symbolize eating (drinking) blood.
