Some Protestant sects, such as the Puritans, banned gift-giving in the American colonies, as well as any other recognition of the Christmas celebration. One could be placed in stocks or even flogged if one closed one’s shop in recognition of December 25.
The early Church did celebrate the birth of Christ - we have textual evidence as early as 200 A.D., which means the practice went back even earlier (the earliest textual evidence does not mean a practice sprung up spontaneously on that date, but must be presumed to have existed even earlier), although there were regional differences over which date should be celebrated. Giving gifts may or may not have been part of early celebration, but there is no evidence the Catholic Church “banned” such celebrations. Tertullian didn’t like Christians joining in with pagan New Year celebrations, which did include gift-giving, but that’s about it for the ECFs. He also pointed out that because Christian and pagan celebrate things in the same way or on the same date, that doesn’t mean the practices share a common origin:
 Others, again, certainly with more information and greater verisimilitude, believe that the sun is our god. We shall be counted Persians perhaps, though we do not worship the orb of day painted on a piece of linen cloth, having himself everywhere in his own disk.  The idea no doubt has originated from our being known to turn to the east in prayer. But you, many of you, also under pretence sometimes of worshipping the heavenly bodies, move your lips in the direction of the sunrise.  In the same way, if we devote Sun-day to rejoicing, from a far different reason than Sun-worship, we have some resemblance to those of you who devote the day of Saturn to ease and luxury, though they too go far away from Jewish ways, of which indeed they are ignorant.
We should also note that Christ ordered that whatever we do to the least of our brothers, that we do unto him. So alms-giving was long a part of the Advent celebration in the Catholic Church. The gift of money, food, clothing for the poor, and I assume, toys for poor people’s children - are ordered by Jesus and should be an important and appropriate part of Christmas, as Catholic saints such as Nicholas and Wenceslas often did. As gifts given to friends and family and neighbors in the sincere hope of making their lives easier, or simply making them happy are also an act of charity, done in the name of Jesus, I suspect that Jesus Himself does not disapprove. The gifts of the Magi to honor the birth of the Redeemer are not presented in the Bible as a bad thing, but as a recognition and glorification of His birth.
So, your friends on Facebook should ask the Puritans’ modern descendants, such as the Congregationalists, and the neo-Puritan sects who object to the celebration of Christmas, why they banned the practice, not the Catholics.
Hope this is helpful to you. Merry Christmas!
