If you are looking at ministry in the SBC it would be strange if you didn't view infant baptisms as nullities. However, if you are simply looking at being a member of an SBC church while you pursue studies, and plan to pastor outwith that denomination the situation could be different.

As a paedobaptist in a country where most Reformed churches are baptist I have mused over what I would do if the only decent local church to join was a baptist church. I think I would be anabaptised, not because I think my first baptism was invalid, but so as not to put a stumbling block in the way of participation in church life. ISTM participation as a member of a local church is more important than making a stand on this issue when I am free in my own conscience to decide which baptism to consider as authentic. It can also be seen as a weaker brother/stronger brother issue. One is seeking not to offend weaker brethren in the church and voluntary circumscribing one's liberty for the peace and unity of the church.

Yours in Christ,

James.
