Your hyper literalism is deceiving you, Now where does Scripture tell us the Christ rose on Saturday. This reliance on self leads to all sorts of silly and downright dangerous notions like Sabbath resurrection, keeping kosher law, sola scriptura, Arianism, Pelagianism, Adoptionism, Montanism and a host of deviations from orthodox Christianity. When one seeks only to disprove the teachings of the Chruch, they all to often "disprove" orthodox Christianity in favor of a unique version of Christianity that may as alien to the truth as Islam is.
It's a narrow path, there is one guide and He gave us a Church so that we may better discern that path. Don't walk alone.
