Do you mind if I ask a question?
"Does 'conditionally ordained' mean that they were ordained in the TRIDENTINE rite?" "Are all SSPX Tridentine rite?"
A conditional ordination is done when there is positive doubt to the validity of a priest's ordination, as there is for many traditionalists regarding the new episcopal and priestly ordination rites.
In the case of traditional groups, conditional ordinations are usually done when a priest defects from the Novus Ordo. He is then conditionally ordained by an undoubtedly valid bishop using an undoubtedly valid rite (yes, the Tridentine rite). It's the same principle as a conditional baptism or confirmation, and within the prayers the person administering the rite usually says something to the effect of 'If you are not already ordained/baptized/confirmed...' or 'If you can be ordained/baptized/confirmed' It is not a RE-ordination (such a thing is sacrilegious) but a conditional one, as a result of positive doubt.
To S2Srea, it is the furthest thing from detraction. The faithful have a right to know that they are being ministered to by real priests, and the traditional clergy have a duty and obligation to ensure it.
