Cekada and the others took the same position on the Thuc line as Kelly and then changed later on. If you want to take your chances with Thuc clergy, go ahead( although I found it odd given that I seem to recall you saying you used to work with SSPV. Change of position on this question?)
At least Father Cekada was humble enough to admit he was wrong years ago.
Allow yourself just a short escape from your years (?) of anti Thuc indoctrination and I can assure you, if you are just a little bit reasonable, that if you read Mario Derksen’s study, you will come to the realization that the SSPV’s position is unequivocally wrong. In fact, what you will find is if you use the same criteria Bishop Kelly applies to the Thuc line and apply it to the Mendez line, you will see that the Thuc line is far more credible when it comes to validity.
