No, this was said "Ex portas inferni" = "from the gates of hell." However, so-called "infallible" statements are not the only magisterial level of teaching which popes have taught require assent. For popes have also taught that,
'the one duty of the multitude is to allow themselves to be led, and, like a docile flock, to follow the Pastors," "to suffer themselves to be guided and led in all things that touch upon faith or morals by the Holy Church of God through its Supreme Pastor the Roman Pontiff," "of submitting with docility to their judgment," with "no discussions regarding what he orders or demands, or up to what point obedience must go, and in what things he is to be obeyed... not only in person, but with letters and other public documents ;" and 'not limit the field in which he might and must exercise his authority, " for "obedience must not limit itself to matters which touch the faith: its sphere is much more vast: it extends to all matters which the episcopal power embraces," and not set up "some kind of opposition between one Pontiff and another. Those who, faced with two differing directives, reject the present one to hold to the past, are not giving proof of obedience to the authority which has the right and duty to guide them," "Nor must it be thought that what is expounded in Encyclical Letters does not of itself demand consent."

And as for "infallible" statements, this is an unscriptural presumption which is based upon Rome infallibly declaring herself conditionally infallible. Rome has presumed to infallibly declare she is and will be perpetually infallible whenever she speaks in accordance with her infallibly defined (scope and subject-based) formula, which renders her declaration that she is infallible, to be infallible, as well as all else she accordingly declares.
Which is only one of the many distinctive Catholic teachings are not manifest in the only wholly inspired substantive authoritative record of what the NT church believed (which is Scripture, in particular Acts through Revelation, which best shows how the NT church understood the gospels).
