Some are being misled by following a calendar that starts the year and the weekday count on the Spring Equinox date, and claiming that doing so is Scriptural.
However, this would deny the Christ prophesied to die on the 14th day (Passover) of the first month of God's calendar and arise 3 days later, because they are believing in a Christ that rose the very next day on a Sunday, the first day of the week, and the 14th would always be a Saturday with such a calendar.
Clearly, such a discrepancy should cast doubt on the logic and credibility of the proponents of this type of calendar.
Also, aligning this "SUNDAY SAVIOR" with the observance and endorsement of the ancient custom of "Easter" (Astarte) should make it obvious that a pagan-oriented agenda is motivating it.
