Wow! You don't know what you are talking about!
From the Seventh Day Adventist's official website:
2. Trinity:
There is one God: Father, Son, and Holy Spirit, a unity of three co-eternal Persons. God is immortal, all-powerful, all-knowing, above all, and ever present. He is infinite and beyond human comprehension, yet known through His self-revelation. He is forever worthy of worship, adoration, and service by the whole creation. (Deut. 6:4; Matt. 28:19; 2 Cor. 13:14; Eph. 4:4-6; 1 Peter 1:2; 1 Tim. 1:17; Rev. 14:7.)
From the official Church of God offices website:
In one God eternally existing in three persons; namely, the Father, Son, and Holy Ghost.
The United Pentecostal Church IS Anti-Trinitarian - but is considered a cult. It is not the Pentecostal church.
The Unification Church isn't even Christian.
Unitarian Universalists are also a cult.
Christian Fellowship isn't even a denomination.
If you are referring to Intervarsity Christian Fellowship, This is from their website:
We believe:
The only true God, the almighty Creator of all things,
existing eternally in three persons–
Father, Son, and Holy Spirit–full of love and glory.
The internet is full of non-trinitarian links. Helps yourself.
