Again, that does not say do not celebrate The Feast. Colossians 2:8 certainly does not nor does Mt 15:3, that has to do with dietary laws and washing hands, nothing to do with keeping the memorial of Christ resurrection.
St Paul in 1 Corinthians 5:6-8 (which was one of the assigned Readings at the Sunday Liturgy for the Epistle reading {a Reading from Colossians was also available) says “..For Christ our paschal Lamb has been sacrificed. Let us therefore celebrate the festival, not with old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth”
The Eucharistic imagery here is clear, and the connection to the Jewish Pasaover feast is clear, thus the Celebration “Festival” referred to here is clearly referring the Church gathering together to commemorate the Passion, Death and Resurrection of Christ by partaking of the Eucharist. The writings later in Chapter 10: 14-22 and 11”23-32 continue this theme.
And again, the celebration of Pascha predates Bede by centuries, as the link I provided clearly indicates.
Matthew 15:8-9
8
‘These people draw near to Me with their mouth,
And[a] honor Me with their lips,
But their heart is far from Me.
9
And in vain they worship Me,
Teaching as doctrines the commandments of men.’
