No it's not. Modalism says that God manifests himself in different modes depending on the circumstances. That's not what I'm talking about. I asked you to define modalism earlier and you couldn't/wouldn't do it. Now you're trying to tell me what it is?
Modalism is a Christian theological belief that God is one person who appears in three different forms, or modes, rather than three distinct people. It's also known as Sabellianism or modalistic Monarchianism.
How it's taught
Modalism was first taught by Noetus of Smyrna in the second century.
Praxeas and Sabellius also taught modalism in Rome.
Adolf von Harnack coined the term "Modalism" in his 1897 book History of Dogma.
What it teaches
God is one person who manifests as the Father, Son, or Holy Spirit.
The Father, Son, and Holy Spirit are not three distinct people, but rather three modes of God's activity.
The Father, Son, and Holy Spirit are successive manifestations of God.
God's person is one and reveals himself to creation through different modes.
What it's compared to
Modalism is a form of Monarchianism, which is opposed to Trinitarianism.
Modalism is also known as Patripassianism because it implies that the Father suffered on the cross.
What it's associated with
Modalism is embraced by many groups in the United Pentecostal Church International (UPCI).

Sabellianism is a theological doctrine that teaches that
God is one person who manifests in three aspects: the Father, the Son, and the Holy Spirit. Sabellianism is also known as Modalism.
Aspects of Sabellianism
Unity of God
Sabellianism emphasizes that God is one person, and that the Father, Son, and Holy Spirit are different manifestations of that person.
No personal relationships
Sabellianism denies that the Father, Son, and Holy Spirit have personal relationships with each other.
Three modes
Sabellianism teaches that God reveals himself in three modes, or aspects, which are the Father, Son, and Holy Spirit.
Analogy of the sun
Sabellius used the sun as an analogy for God's nature, suggesting that God has three powers like the sun: warmth, light, and circular form.
Three masks
Some Modalists suggested that God would put away the masks of the Father, Son, and Holy Spirit after redemption and manifest himself as one person.
Sabellianism is considered heresy by most Christian groups that believe in Trinitarianism.
