Also, many Catholics call themselves celebrating the baptism of Jesus by taking a dip outside in the cold waters on the first Sunday after January 6th every year. It is called the celebration of Epiphany, another pagan ritual. The person will strip down in the cold weather and walk into a body of cold water, cross their heart up and down and side to side, and then immerse themselves into the water. Take note that when a person first comes to be baptized into the Catholic Church, they will only pour or sprinkle water on their head in a false attempt to obtain remission of sins.
This scripture in Acts, where it mentions the holiday of Easter, was not referring to the resurrection. Even way back then, the pagan practice of Easter eggs was in place.
