For Catholics, Easter in the most important religious event during the whole year. But not everybody remember, where some of the traditions came from. Here you will find explanation. Poles celebrate this event and on Easter Saturday morning we go to church with willow basket which should content eggs, bread, sausage, horseradish, salt and pepper.  
“We consecrate the lamb, in remembrance of the true Lamb of Christ and His Triumph and we decorate the roast lamb in honour of this” – said Father Newerani in 1739

 at “The Ornament of the Catholic Church”. According to the Old Testament, the lamb was the sacrificial animal to be offered to Jehovah. According to Christian tradition, the lamb is the symbol of Christ’s suffering on the cross.
“We consecrate the horseradish in remembrance of the day when the bitterness of Christ’s suffering changed into sweetness and joy. Therefore we also consecrate the butter, which symbolises that sweetness”. Every member of the household should try the horseradish, even the little children. Peasants in the Silesia region of Poland used to eat the horseradish with a spoon, as they saw it as a symbol of Christ’s suffering. “Finally we consecrate the eggs. Just as the hen gives birth to the chick twice (once by carrying the egg and again by incubating it), so we are twice reborn through Christ”.
One legend links the tradition of painting eggs to Mary Magdalene. When the angel told her of Christ’s resurrection, she returned home in a state of great joy and noticed that the eggs that she had been carrying had turned red. She gave the eggs to the apostles and they turned into birds in their hands, convincing them of Christ’s spiritual transformation. According to another legend, Mary painted the eggs different colours in order to bring joy to the young Christ.
Bread has always been a symbol of fullness, prosperity and the blessing of God. Many saints – for example Benedict, Anthony and Paul the Hermit – thought that bread was brought by the birds, as a symbol of the mercy of the Heavens. Breaking bread with someone was a symbol of friendship and hospitality, but to refuse to break bread with the poor was a great sin.
According to Jewish tradition, salt is a symbol of Jehovah’s Covenant with his people. The law of the Old Testament dictated that all offerings to God should contain salt. Thanks to its use as a preserving agent, salt symbolises purity, permanence and holiness. In his Sermon on the Mount, Christ called the Apostles “the salt of the earth”.
