We should be careful. It really isn't worth celebrating until he actually comes over like Bishop Lazo did. Bishop Lazo, RIP, had the humility to start co-operating with the traditional Bishops and publicly associating with them. So far we have not seen that from Bishop Vigano.
It is always telling when Ecclesia Dei people get all worked up about something compared to when they go quiet. The former is an indication that there is something to be suspicious of.
