I challenge you to find anyone, before the very confused Fr. Feeney, who said a person that died in the state of grace, but unbaptized, might go to heaven.
Here's five:
POPE INNOCENT III: You have, to be sure, intimated that a certain Jew, when at the point of death, since he lived only among Jews, immersed himself in water while saying: “I baptize myself in the name of the Father, and of the Son, and of the Holy Spirit. Amen.” We respond that, since there should be a distinction between the one baptizing and the one baptized, as is clearly gathered from the words of the Lord, when He says to the Apostles: “Go baptize all nations in the name etc.” (cf. Matt. 28:19), the Jew mentioned must be baptized again by another, that it may be shown that he who is baptized is one person, and he who baptizes another
... If, however, such a one had died immediately, he would have rushed off to his heavenly home without delay because of the faith of the sacrament, although not because of the sacrament of faith (Debitum pastoralis officii, August 28, 1206:Denzinger 413).
Pope Innocent III (12th Century): "
We assert without hesitation (on the authority of the holy Fathers Augustine and Ambrose) that the 'priest' whom you indicated (in your letter) had died without the water of baptism, because he persevered in the Faith of Holy Mother Church and in the confession of the name of Christ,
was freed from original sin and attained the joys of the heavenly fatherland." (Denzinger 388)
Pius XII: "If what We have said up to now deals with the protection and the care of natural life, it should hold all the more in regard to the supernatural life which the newly born infant receives with Baptism. In the present economy there is no other way of communicating this life to the child who has not yet the use of reason. But, nevertheless,
the state of grace at the moment of death is absolutely necessary for salvation. Without it, it is not possible to attain supernatural happiness, the beatific vision of God
. An act of love can suffice for an adult to obtain sanctifying grace and supply for the absence of Baptism; for the unborn child or for the newly born, this way is not open..." (Address to the Congress of the Italian Catholic Association of Midwives)
St. Bernard of Clairvaux, Doctor of the Church (12th century): Letter No.77, Letter to Hugh of St. Victor, On Baptism: “If an adult...wish and seek to be baptized, but is unable to obtain it because death intervenes, then where there is no lack of right faith, devout hope, sincere charity, may God be gracious to me,
because I cannot completely despair of salvation for such a one solely on account of water, if it be lacking, and cannot believe that faith will be rendered empty, hope confounded and charity lost, provided only that he is not contemptuous of the water, but as I said merely kept from it by lack of opportunity..."
St. Thomas Aquinas: " I answer that, the sacrament of Baptism may be wanting to someone in two ways. First, both in reality and in desire; as is the case with those who neither are baptized, nor wished to be baptized: which clearly indicates contempt of the sacrament, in regard to those who have the use of the free will. Consequently those to whom Baptism is wanting thus, cannot obtain salvation: since neither sacramentally nor mentally are they incorporated in Christ, through Whom alone can salvation be obtained.
“Secondly, the sacrament of Baptism may be wanting to anyone in reality but not in desire: for instance, when a man wishes to be baptized, but by some ill-chance he is forestalled by death before receiving Baptism.
And such a man can obtain salvation without being actually baptized, on account of his desire for Baptism, which desire is the outcome of faith that worketh by charity, whereby God, Whose power is not yet tied to visible sacraments, sanctifies man inwardly. Hence Ambrose says of Valentinian, who died while yet a catechumen: 'I lost him whom I was to regenerate: but he did not lose the graces he prayed for.' " Summa, Article 1, Part III, Q. 68:
