Did not Christ show us how to celebrate passover with the last supper? Why not just have a communion on passover? Christian congregations do not.
The ceremonial laws of Moses were pointers to Christ. Christ having come, we no longer need the pointers.
The WCF puts it like this:
>3. Beside this law, commonly called moral, God was pleased to give to the people of Israel, as a church under age, ceremonial laws, containing several typical ordinances, partly of worship, prefiguring Christ, his graces, actions, sufferings, and benefits; and partly, holding forth divers instructions of moral duties. All which ceremonial laws are now abrogated, under the new testament. (WCF XIX.3)
See: Col. 2:14, 16–17; Dan. 9:27; Eph. 2:15–16; Heb. 9:10; Acts 10:9–16; Acts 11:2–10.
In the Lord's Supper, we are remembering something different than what is remembered in the Passover. "Do this in remembrance of _your deliverance from Pharoah_" gets superseded by "Do this in remembrance of ME." Rather, we might say that Christ _fulfilled_ the Passover, revealed its true meaning, and changed how we celebrate it. Either way, the Mosaic "way" is ceased.
> Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come, but the substance belongs to Christ. (Colossians 2:17-18, ESV)
These are good questions, but the answers are right there. The question of 'what do we do with the Mosaic law 1) as gentiles; and especially 2) now that Christ has come?' is addressed by the Jerusalem council (Acts 15), and by Paul in most of his Epistles (Romans, Ephesians, Colossians, Galatians, etc.), and especially in the Epistle to the Hebrews (whether written by Paul or another).
> For since the law has but a shadow of the good things to come instead of the true form of these realities, it can never, by the same sacrifices that are continually offered every year, make perfect those who draw near. (Hebrews 10:1, ESV)
