No.
CCC 1261 does not preclude limbo, but, in fact, encourages us to believe in it, for the “hope” of “a way of salvation” for unbaptized infants, when considered against the background of Catholic tradition and the dogma of original sin and its penalties, should be understood to be the hope for the unending natural happiness of limbo, not the *supernatural *happiness of heaven.
Unbaptized infants cannot attain the supernatural happiness of heaven for this reason: they are, in some sense, punished in the next world. It is a Catholic dogma, not a mere theological hypothesis, that “the souls of those who die mortal sin or in original sin only descend without delay into hell, to be punished, however, with different kinds of punishments” (DS 858=D 464 and DS 1306=D 693). This punishment is deprivation of the beatific vision (DS 780=D 410).
Since children dying without the urgently necessary sacrament of Baptism are deprived of the supernatural happiness of the beatific vision in accordance with the DS 858/1306 dogma, then how can we say, as *CCC *1261 states, that may hope for a kind of salvation for unbaptized infants? We can say this only because limbo, which is unmerited, unending natural happiness provided by God’s goodness, mercy, love, and universal salvific will, can be viewed as a kind of salvation, a quasi-salvation. After all, the unbaptized child is saved from the pains of hell.
Keep and spread the Faith.
