In addition to the obvious modalism, I take great issue with anyone who has the words 'baptism of the Holy Spirit' (usually because people misuses the phrase whenever they use it in a doctrinal document), and requires such baptism to necessarily be evidenced by speaking in tongues. Ignoring that I KNOW people who have falsely spoken in tongues in such situations, but that this has been accepted as evidence of their baptism (which really makes it being an 'evidence' or any sort entirely pointless), there's no clear scriptural basis for this first of all as a truth, and second of all as a doctrinal necessity. I mean, if it was a necessary evidence, it almost beggers belief that there is no evidence that Paul spoke in tongues at such a point in Acts at all, and indeed the only reference is from his own pen in 1 Cor 14 which is nowhere linked to baptism of any sort, and indeed he seems to assume that Christians can be gifted by the Spirit in other (and, he argues, more important ways) without speaking in tongues.
