Catabaptists tend to rely more on the latter baptism itself than upon the Triune God to validate that sacrament. Holy Scripture, however, is quite plain. All 'rebaptisms' involve, at least subjectively, a fresh crucifying of Christ. Hebrews 6:1-6. The very idea should make Christians shudder. For Christ died but once and for all. In baptism, we too died once and for all. Romans 6:1-13.
Now Romish Catabaptists opt for an ex opere operato view of the sacrament. Thereby, baptism itself is deemed to cleanse. Although in theory they claim that 'Protestant baptisms' are quite valid -the Romanists' very insistence upon baptism as such, has expanded their giving 'conditional baptisms' to many and perhaps even to most Ex-Protestants who romanize. This itself makes such Romanist 'conditional baptizers' de facto Catabaptists.
