They were convinced by Jews to observe special days.
Convinced? They were converts...they wanted to join. You are insinuating that these new believers wished to play ball with the team but not wear the uniform much less keep the rules of the game...laughable.
They crowded synagogues everywhere on Sabbaths to hear about One resurrected from the dead and heard the Torah read to them as James said at the council.
What the issue became was that there were those from "the tribe" who began to insist gentiles be circumcised to be saved or even allowed to hang out with them...that was an error as even Abraham was chosen and considered righteous before being circumcised Moses too...
When you join a club you usually go along with the club rules...especially the traditional ones, the rules that define the club, the ones written by the Founding members. See? Then ya get the benefits of being in that club...And not just lost in some faceless crowd.
Since Jesus, the observance of special days is not worthless.
Typo? Or which special days are you meaning? These?
Nativity
the Epiphany,
the Ascension,
the Body and Blood of Christ,
Holy Mary the Mother of God,
her Immaculate Conception,
her Assumption,
Saint Joseph,
Saint Peter and Saint Paul the Apostles,
and All Saints.
They are obligated is true...and people who wish to be in the Church willingly do so...
It's usual to do something because you are a member not to become one...
