Why does the Orthodox Creed not mention any sacraments other than baptism?

The answer

First: Baptism used to be a controversial subject. There have been controversies over situations such as those who were baptized by a priest but then denied their faith due to extreme persecution, or those who were baptized by heretics and then sought to join the Church.

Second: At that time, there were no controversies about the other sacraments.

Third: The Church wants her children to be proud of being the children of God through baptism.
