QUOTE : Christ promised to baptize his disciples with the Holy Spirit,41 and on the day of Pentecost, fulfilled his promise by pouring out the Spirit upon them.42 Here, it is said, the pouring out of the Spirit is compatible with the supposition, that sprinkling or pouring is baptism, but not with the supposition, that immersion only is baptism. This objection derives all its force, from the erroneous supposition that the baptism of the disciples consisted in having the Spirit poured out upon them. But if the pouring out of the Spirit proves that pouring is baptism, their being filled with the Spirit proves that filling is baptism.
