From what I have seen and heard of him in the past, Father Ballini seemed like a good and devout priest.
I have hopes for Ireland having him as a bishop and Father Chazal seems to support him and think we'll of him. (I noticed he shared a post today about his being Resistance Bishop #5).
And as for the "consecrating in secret"... It may have caused less drama to have made it more public, but I can understand why it may have been kept more quiet. There is SO MUCH drama in the traditional movement these days. And... Apparently Father Ballini made several enemies during COVID who would probably have tried to stop the Consecration from happening if they could have and knew beforehand.
