There are those who believe that only the 12 were filled with the Spirit and spoke with tongues in Acts chapter 2. Some connect the last verse in chapter one with the first verse in chapter two and come to that conclusion.
At the time of the outpouring of the Holy Spirit in Acts chapter 2 there were more than 500 believers according to Paul in
1 Corinthians 15:6, but according to the way I understand
Acts 1:15 only about 120 of them were filled with the Spirit on that day. That does not trouble me because I realize not all Christians receive the Holy Ghost Baptism (as we Pentecostals define it) in our day. I know good Christians that do not speak with tongues --actually I know good Christians that do not even believe that speaking with tongues is a valid experience for today.
Personally, I consider myself Apostolic or Pentecostal or Charismatic and I pray in tongues just about every day, however I do not consider myself to be superior to other Christians who do not speak with tongues.
