The most obvious thing to be said about Christianity is that it rests on historic facts: the Creation, the Incarnation, and the Resurrection. Since our doctrines are truth claims, they cannot be mere symbolism.. This is important to remember as we celebrate the Resurrection, which is often clouded by the pageantry of Easter. It's difficult to make people understand that God's Holy days are listed in the bible. It's interesting too that Jesus says to observe his death on Passover yet this message is obscured by traditional Christianity's insistence on creating its own holidays.
