Soulcore is in good standing with the Church. I don’t know if they are in the “Catholic Directory” but I know Cardinal Dolan is a fan (one of Soulcore’s founders has a brother who is a diocesan priest in the Archdiocese of New York)
And it’s been mentioned at least three times in the National Catholic Register: http://www.ncregister.com/search/results?q=soulcore
Personaly, I met the two ladies who founded SoulCore and had a lengthy discussion with one of them (the one who’s brother is a priest). They are very dedicated to making sure everything is 100% in line with the Catholic Church and even made sure they have not stretching positions that are religious positions in Yoga.
I highly recommend them.
Here’s an TV interview from NET TV (a Catholic TV network from New York): https://www.youtube.com/watch?v=PLaVYUgQw58
This is good to watch and you can learn more about them
