What are non-ordained lay person powers?

According to apostolic churches (those claiming apostolicity), what powers do the lay people unordained have? For example, both the Church of Rome and the Anglican church agree that a lay person can baptise in an emergency: [Emergency Baptism](https://www.churchofengland.org/prayer-and-worship/worship-texts-and-resources/common-worship/christian-initiation/emergency-baptism) . 1284 In case of necessity, any person can baptize provided that he have the intention of doing that which the Church does and provided that he pours water on the candidate's head while saying: "I baptize you in the name of the Father, and of the Son, and of the Holy Spirit." (CCC)
