That is a good verse, John 8:32. Same for you, Mike. Those need to be read and considered especially by guys like us so that we don't fall into the same pit as the Pharisees.
I believe I can speak for nmwings concerning this, but we are not condemning. We are not saying you will lose salvation, grace, love or that you are a horrible person. That would be condemning and judging. That is not our place, but just as Jerimiah pleaded that Jeruselem stop their abominations, we are too. It isn't our opinion that these are abominations, but God's. He said to no even learn their practices.
I am not even saying that you must follow OT feasts, just don't follow pagan festivals. I would rather have missed out on Easter than be caught teaching the traditions of man. Easter is exactly that. Man Made, not God appointed. I know that Easter doesn't mean you like Eostre or Ishtar, but that is not what matters. What does God think? God turns those away who do not follow his instructions and welcomes those who do. Cain and Able is an easy example.
Simple study reveals the origin of Easter. Grab an encyclopedia. I am not saying to do Passover, just don't do Eostre.
I am saying to keep the Feast Days, they reveal God's plan of salvation. As far as Passover and the Days of Unleavened Bread...
In John 13 Jesus Christ changed the Passover symbols to Unleavend Bread, Wine and the foot washing service...
John 13:15 For I have given you an example, that ye should do as I have done to you.
16 Verily, verily, I say unto you, The servant is not greater than his lord; neither he that is sent greater than he that sent him.
17 If ye know these things, happy are ye if ye do them.
These are some of the last instructions He gave the Apostles just before His crucifixion. But what about the Days of Unleavened Bread?
1 Cor 5:6 Your glorying [is] not good. Know ye not that a little leaven leaveneth the whole lump?
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:
8 Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened [bread] of sincerity and truth.
Here Paul admonished a gentile church in Corinth to keep the Days of Unleavened bread and shows that there is deep spiritual meaning in them.
