I remember when I first went to a Pentecostal church. I thought it was strange and kinda scary, but at least they gave interpretation of tongues. The Charismatic churches I went to later did not, and I could never really tell if the tongues being spoken were of God or not.
My mother grew up in a pagan household of Europeans who had largely given up their Christian beliefs. Somehow she became attracted to Christianity, and went into a Pentecostal Church, which frightened her off. Then she attended a Lutheran Church, which was less frightening, and stuck there ever since.
And so we were raised in Lutheranism, though my Mother's brother later became Pentecostal. The Christianity of both my uncle and my Mother were sincere, but Lutheranism was so weak that it didn't prevent me from participating in my generation's waywardness. Only when I ended up in detention did I begin to seriously repent and return to Christian living.
I was the 1st in my family to turn to Pentecostalism/the Charismatic movement (about 17 years old). Since I was not raised up in a Pentecostal Church I was more Charismatic than Pentecostal, not seeing much of a dividing line between Christians, whether Pentecostal or other.
I did recognize, however, that the Pentecostals, in focusing on the Holy Spirit, seemed to more often have a deeper commitment to Christian living. But it was not exclusively so, there being many Baptists, and Holiness Church members, as well as others, who were as committed to Christian living as Pentecostals.
Tongues was pretty much being forced on me, doctrinally, and so I ultimately turned against it for myself. I felt like I was performing, and not being led, and found, at any rate, that Paul taught a diversity of gifting, as opposed to what the Pentecostals taught, that "all" should speak in a prayer language.
Anyway, I don't let small issues like this and other peripheral differences divide me from other Christians. I'm Postrib whereas most of my friends are Pretrib, and I simply state my beliefs and let others believe as they feel led.
I love honesty, and walk away from emotional outbursts over doctrine. Setting an example of love and temperance is, I feel, very important. Our example is what witnesses to others, who are looking for "the Way."
