I think another important question is whether or not they even have a valid line of Apostolic Succession considering they call themselves an Apostolic Church. If the line of Succession was broken, they have no Apostles and therefore their Holy Orders, Confessions, and Holy Eucharist are all invalid. That means no Holy Spirit at Holy Orders, no real Absolution at Confession, and no Real Presence of Jesus Christ in the Holy Eucharist (as in - the Eucharist in their churches is really not the Holy Eucharist and is really just bread and wine - similar to a Lutheran church or an Episcopalian Church).
Heresy and Schism… really put people in danger of losing their souls
