The Bible testifies that the kingdom of heaven and salvation are given to those who keep God’s perfect law of the new covenant, but that those who keep the changed laws will be punished forever.

The perfect laws of the new covenant―the Sabbath, the Passover, baptism in the name of the Father, of the Son and of the Holy Spirit, etc.―were all destroyed during the Dark Ages and instead men’s rules were made―Sunday service, Christmas, etc.
