What is pantheism (tying Wordsworth into the answer)?
Pantheism, according to Merriam Webster, is
a doctrine that equates God with the forces and laws of the universe.
Therefore, any work which equates God as the ultimate creator of all which exists on earth and in the universe would equate as a pantheistic text.
William Wordsworth (1770-1850) is a renowned Romantic poet. Typical characteristics of the themes which lie in Romantic literature encompass the theology which supports Pantheism.
Romantics, and therefore Wordsworth, found nature to be an integral part of the lives of man.
During Wordsworth's youth, he was a political radicalist. Later in life, he embraced religious theology and was known for his commitment to Christianity. Wordsworth was known for stating that he would lay down his life for the Church and his text Ecclesiastical Sketches reitterated the fact.
