I remember our history profesor at Pentecostal Seminary- Paul Sheppard, who said that it is good for us (different denominations) to learn from each other.
The musical accompaniment in Protestant communities is quite rich, and if it enriches the Christian heritage of the youth meetings of the Church, it is only for edification.
Pastors of charismatic Protestant communities should be more likely to look in the Catholic catechism, for that would not be in the wilds of some psuedo-Christianity, but there is nothing wrong if the Protestant hymn or song for the glory of the Lord adorns and enriches the Catholic Divine-service.
The main thing that it is for the glory of the Lord.
