And we have generally accepted the validity of heretics' Baptism, as long as there is proper form.

Well; I SURE don't wanna make any 'erroneous assumptions' about what proper form means; so I'll await your definition.

[Claud]

Proper form of Baptism generally means water and the Trinitarian formula: “I baptize thee in the name of the Father, the Son, and the Holy Ghost”.

Baptism in Jesus’s name alone, or according to other language like “Creator, Redeemer, and Sanctifier” is invalid.
