You can’t determine this decisively from the sources provided to me here, because they do not contain any specific statement by Pope Leo XIV (or his official texts) on “Augustine’s Christology.” So I cannot responsibly answer “yes” or “no” as a matter of evidence.

What I can do is explain how such an emphasis would fit Catholic categories, and what Catholic sources affirm about Augustine’s enduring role.

1) What the Church can say: Augustine’s doctrinal importance is not new

Catholic magisterial teaching consistently presents St. Augustine as a major theological authority. Pope John XXIII, for example, explicitly calls Augustine “Doctor of divine grace” in the Church’s memory and highlights Augustine’s role in defending the faith against Pelagianism, which concerns how Christ’s saving grace works in human life.1

Even though that text is not focused specifically on “Augustine’s Christology,” it shows that Augustine has long been treated as a central voice for Christ’s saving work as received in grace—precisely the area where Christology and soteriology (Christ as Savior) meet.1

2) How a “renewed Augustinian influence” could be recognized (without claiming it has happened)

In Catholic practice, when the Church experiences a “renewed emphasis” on a Father, it typically functions as a retrieval and re-interpretation within Tradition, not a replacement of other parts of the deposit of faith.

For instance, the Dicastery for Promoting Christian Unity describes “re-reception” (and related processes of re-interpretation) as a kind of rediscovery/sifting where elements are “read” more faithfully and fruitfully in a new context, while remaining faithful to original intention.2 3 4 It also stresses the hermeneutical rule that earlier doctrinal teaching must be read in the light of later conciliar development (e.g., Vatican II for Vatican I), clarifying terminology and avoiding misleading readings.5

So, if Pope Leo XIV has emphasized Augustine’s Christology, then in principle this could reflect a renewed Augustinian influence in exactly this Catholic sense: a fresh remembrance and further clarification of themes already belonging to the Church’s inheritance—especially those that help the Church articulate Christ’s person and saving work clearly today.2 5

3) What would count as stronger evidence of renewal

To say the emphasis is truly “renewed” (rather than simply “present”), you would normally look for signs like:

• repeated magisterial citations of Augustine in Christological teaching (not just occasional reference),
• a clear pastoral/theological program drawing out Augustinian Christological implications,
• and an explicit link to contemporary doctrinal challenges (e.g., grace, incarnation, the Church’s unity, worship/Eucharist, etc.).

None of that can be confirmed from the provided sources, because there is no direct Leo XIV–specific material here.

Conclusion

• From the provided sources: I cannot establish whether Pope Leo XIV’s emphasis reflects a renewed Augustinian influence, because those sources don’t document his emphasis.2 3 4 5
• What Catholic teaching supports: Augustine is unquestionably a major doctrinal authority in the Church’s tradition (notably for divine grace), and an official papal emphasis on a Father would fit a recognizable Catholic pattern of “re-reception” and renewed interpretation—if it is presented in continuity with the whole Tradition and in harmony with the conciliar hermeneutic.1 2 5

If you share the specific Leo XIV statement(s) you mean (or link/quote them), I can assess the claim directly and with tighter fidelity to the text.
