Yap, this is an old but true and if it's new it's not true. Baptismal regeneration is not a first century teaching of the New Testament church but rather errors brought by erring churches later adopted by the Catholic Church, popularized by Campbell and the existence of the so called "new wave" churches in all sorts.Two workings of the Holy Spirit. The new birth/baptized by one Spirit into one body (1 Corinthians 12:13). The "infilling" of the Holy Spirit (Acts 2:4). By "labeling" the "infilling" of the Holy Spirit as "baptism of the Holy Spirit," it sounds like you are confusing the two workings.
