At the time of Christ, because of historical deviation, some kept Passover at home at the start of the 14th and others kept it at the Temple at the end of the 14th.
Was Jesus Christ's body actually broken? If so, it would have symbolized disqualification and a broken covenant. Only the bread of Passover was broken.
God asks that we use the Passover to bring to remembrance His redemptive act, especially how our sins caused Christ to die in our stead.
If we do not keep God's holy days, we will deprive ourselves of the knowledge of God's purpose. Jesus and the first century church observed and upheld these days.
Human tradition and Bible truth regarding the timing of Christ's crucifixion and resurrection do not square. Here is the overwhelming chronological evidence.
