Yes. Catholic doctrine does not treat the body’s mortality as incompatible with eternal life; it teaches that eternal life includes the resurrection and glorification of the body, not just the survival of the soul. 1

Death does not end the person—yet the body is mortal

In death, the soul is separated from the body, and the body decays while the person awaits a definitive reunion. 1
Catholic teaching therefore takes seriously the real “mortal” condition of the body, rather than denying it. 1

Eternal life is completed by the resurrection of the body

The Church’s faith includes the resurrection of the dead as “an essential element of the Christian faith from its beginnings.” 1
More specifically, Catholics profess that the dead will rise with their own bodies—resurrection of the body, not merely the soul’s “escape” from matter. 2

The Catholic encyclopedia explains this with two key dogmatic points:

• The risen person is not an unrelated body: the Council teaches that one “will rise again with their own bodies.” 2
• Scripture and doctrine exclude the idea that resurrection means only the rising of the soul from sin to grace. 2

How mortality is reconciled: incorruption and transformation

Catholic doctrine reconciles mortality with eternal life by teaching that God will grant the bodies incorruptible, immortal life and transform them.

The Catechism describes the “how” in these terms:

• God will definitively grant incorruptible life to the bodies by reuniting them with their souls through the power of Christ’s Resurrection. 1
• Resurrection means that “this mortal nature must put on immortality,” and what is “sown” perishable becomes imperishable. 1

The Catechism also emphasizes a crucial nuance: the risen body is the same person in true continuity, but not the same condition—Christ “will change our lowly body to be like his glorious body.” 1
Similarly, the Catholic encyclopedia lists characteristics of the risen body such as identity, entirety, and immortality. 2

What happens to bodily identity?

The Church teaches real identity (“with their own bodies”), while also leaving some details open. For example:

• The encyclopedia notes that nothing is defined philosophically about exactly what constitutes identity between the present body and the risen body, even though the identity-in-resurrection is firmly taught. 3
• Practically, the reconciliation is not explained by physics, but by God’s power and faith in Christ’s Resurrection, which is the model for ours. 1

“How can the body be everlasting?”—the Eucharistic foretaste

The Catechism also offers a concrete “foretaste” of how God can transform what is earthly:

• Our participation in the Eucharist is described as a sign and pledge of the resurrection of the body. 1
• As bread becomes Eucharist by divine blessing, so believers’ bodies “possess the hope of resurrection” and are no longer viewed as merely corruptible. 1

When does this happen?

The Catechism states that the resurrection is definitive “at the last day,” “at the end of the world.” 1
And it connects resurrection closely with Christ’s final coming (Parousia). 1

Bottom line

Catholic doctrine reconciles bodily mortality with eternal life by affirming that:

• the body truly dies and decays, 1
• the soul survives and awaits reunion, 1
• and at Christ’s return God will raise the dead with their own bodies, transforming mortal bodies into incorruptible, immortal, glorified bodies. 1 2
