I am convinced there was a pagan Roman Easter celebration that took place about the time of the Passover...

The practice of spring time egg rolling and quick like a bunny orgies has been practiced for eons. Sadly Christians picked up the pagans rituals and dressed them around our Lord and Savior. Rome sure was not the first but they sure did not keep the leavening out of their doctrine. But they sure are not alone in this practice.
Jeremiah 3:8 (A history lesson that still applies to this day.) And I saw, when for all the causes whereby backsliding Israel committed adultery (spiritually speaking) I had put her away, and given her a bill of divorce; yet her treacherous sister Judah feared not, but went and played the harlot also.
Wonder when did this 'wedding' take place, spiritually speaking of course?
This is how one knows that 'grace' does not cover spiritual adultery/idolatry. First commandment Exodus 20:2 I am the LORD thy God, Which have brought thee out of the land of Egypt, out of the house of bondage.
(Still the very same I am. Christ is the path out of bondage.)
3 Thou shalt have no other gods before Me.
Any one claiming this Commandment is no longer in effect has other gods before Him. And 'grace' of salvation is not given to law breakers. Notice I did not say keeping the law is salvation, it is that salvation is not offered to any who have other gods.
Paul says Christ became our Passover. Nothing about sun-rise services, bunny cakes, or rolling easter eggs.
Oh, best I quote where Paul gave this instruction. ICorinthians 5:7 Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our Passover is sacrificed for us:
No one else could be the Sacrifical Lamb but God with us.
