The logical result of Donatism is to assert that the power of the sacraments comes from the righteousness of the human minister, rather than from Christ himself with the minister being merely a visible mediator or stand-in.
I don't think you really want that.
The main issue of the Donatists was the issue of hermaneutics: how is the Bible interpreted. It is still the issue of today. That one issue decides everything.
- who the fathers where
- baptism
- soteriology (justification, sanctification, glorification)
That is the incongruence between the RCC and Christians, just as it was during the Donatists schism, and it continues to this day. Hermaneutics is the issue, and we will never come together on it.
I personally agree with the Donatist’s on this one - I don’t see a biblical basis for infant baptism.
“The logical result of Donatism is to assert that the power of the sacraments comes from the righteousness of the human minister, rather than from Christ himself with the minister being merely a visible mediator or stand-in.”
I agree with you on this one. This is a grave error.
