I found a link in which a very pagan author, writing on a website called "goddess gift", actually shows the origins of Mother's Day.

Besides the obvious "mother earth" pagan roots of the celebration, and the fact that Jeremiah 10:2 exhorts us not to partake in the way of the heathen, there is also an interesting Talmudic pagan tradition that also reminds me of mother's day.

In Matthew 15:

15:1 Then came to Jesus scribes and Pharisees, which were of Jerusalem, saying,

15:2 Why do thy disciples transgress the tradition of the elders? for they wash not their hands when they eat bread.

15:3 But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition?

15:4 For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death.

15:5 But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me;

15:6 And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition.

The Jews had created their own tradition that allowed them to bring a "gift" to their father or mother in place of actually honoring them. How many Americans today use mother's day as a convenient way to thank their mom but never have a relationship with her for the rest of the year? Many.

Both the pagan roots and scripture command us not to observe this wicked day.
