Pope Paul III, Council of Trent, Sess. 14, Chap. 4, on the Sacrament of Penance: “The Council teaches, furthermore, that though it sometimes happens that this contrition is perfect because of charity and reconciles man to God, before this sacrament is actually received, this reconciliation must not be ascribed to the contrition itself without the desire of the sacrament which is included in it.
Pope Julius III, Council of Trent, Sess. 14, Chap. 4, On Penance: “The Council teaches, furthermore, that though it sometimes happens that this contrition is perfect because of charity and reconciles man to God, before this sacrament is actually received, this reconciliation must not be ascribed to the contrition itself without the desire of the sacrament which is included in it.”
Council of Trent, Sess. 6, Canon 29 on Justification: “If anyone says that he who has fallen after baptism cannot by the grace of God rise again; or that he can indeed recover lost justice, but by faith alone without the sacrament of Penance, contrary to what the holy Roman and universal Church, taught by Christ the Lord and His apostles, has hitherto professed, observed, and taught: let him be anathema.”
One thing is to say: Justification can be restored by the desire for the Sacrament of Penance which is true.. other thing is to declare that desire is enough and/or equal to Baptism of Water.
