Jesus' teaching recorded in the Gospel letters:
Paul's teaching:
1 Corinthians 11: 23-34
1 Corinthians 11:23-26.
Holy Communion helps us grow in grace and helps us become closer to God.
Jesus wanted us to take communion , to show that we believe Jesus died for us.
There really is no telling when human life will end. However, biblical scriptures do tell us that life as we know it will end.
Jesus asked his disciples to eat bread and drink wine in commemoration of the sacrifice of his life, according to scriptures.
It is perfectly OK to tell someone they are not supposed to take communion. However, it often doesn't stop people from wanting to participate in the ritual.
In communion Catholics receive the body and blood of Christ under the form of bread and wine.

The scriptures do not state that the devil has/had a wife. It is doubtful that he does, as the scriptures do tell us that in heaven we will be like angels neither marrying nor giving in marriage. The expression you state "The devil is beating his wife" is an expression referring to a lot of thunder being heard.
No, it is to remind us of Christ's sacrifice on the Cross. Also with the sacrament of communion we gain a special temporal grace which will stay with us until we commit a sin.
Holy Communion
One of my favorites, which shows the heart of God, is found in Isaiah 58 (get a bible or look it up on line and read what the Scriptures tell us).
