The context of my question is the definition of scriptural baptism by your church. Your church will accept some baptisms as valid and thus qualifying for membership. Are there any that it will not accept? Is the mode important to your church? Is the design important? Is the subject important? Is the baptizer important? To put it another way, what are the circumstances under which your church (or you) would say to an applicant for membership, "sorry, you're baptism is in-valid. If you want to join with us, we'll have to dunk you?" I understand that some congregations accept what is commonly called "alien baptism" or "alien immersion." I'm interested in what baptism those congregations would reject. I'll share my views (which some of you already know) after you've had time to chime in and give everybody some grist for the debate mill.
