Nope.
Heb 13:8 Jesus Christ the same yesterday, and today, and forever.

Nope.
Then obviously you did not celebrate a biblical Rosh Hashanah. The commandments for how that day was to be observed are carefully set down in Leviticus and Numbers.
There are no apostolic new covenant rites for celebrating these old covenant feast days. You cannont find a NT verses that says, "Once the temple is destroyed and the levites are no more, keep the old covenant feast days in this fashion." Of course the reason being that the apostles never envisioned Christians following old covenant rituals. They were only a shadow to point people to Christ in the flesh. Once He appeared the shadows serve no useful purpose.
The apostate rabbis after the time of Jesus had to invent new forms for celebrating these days after God destroyed the temple and ended the sacrifices and levitical priesthood once and for all time. Sad to see Christians falling in the same judaizing trap.
Whatever you did was according to the traditions of men. It was an ersatz celebration of your own devising.
