Yes, he introduced "Stealth Arians" as the great enemy of the Roman Catholic Church without mentioning the real threats including Islam.
I found this on Wikipedia page on Arius. If this is the “Stealth Arianism” that Fr. Heilman is talking about, it is NOT, repeat NOT, related to what Arius believed:
“”ARIANISM TODAY — A modern English church called the The Holy Catholic and Apostolic Church of Arian Catholicism claims to follow Arian teachings, canonizing Arius on June 16, 2006.[18] They teach that the Father alone is absolute God, and that Jesus had a beginning, in the flesh, and is subordinate to the Father. They teach that Jesus Christ was the sinless Messiah and Redeemer, however, they do not accept the Virgin Birth, some miracles, the bodily resurrection of Jesus Christ, any divinity or worship of Christ, or Biblical infallibility, placing them in opposition to Arius himself, who accepted all of these, as well as a high-level divinity of Christ. The teachings of the ACAC are more in line with Socinianism than with true Arianism. Whereas Arius himself clearly taught Christ’s pre-existence before Mary, the ACAC does not. The ACAC believe that Jesus was the natural son of Joseph and Mary, with the Holy Spirit overseeing the conception. And they teach that Christ’s resurrection was not in the flesh, but was spiritual. Furthermore, their “Arian Catholic Creed” is a modern creation, not an ancient statement of faith.””
