信仰 means firm belief, faith, persuasion, conviction, and sometimes religion or creed in Chinese, Japanese Kanji, and old Korean Hanja.

This clearly fits the religious connotation of the English word “devotion.”

This is often used to refer to a person of faith or a religious person.

This can be directly translated as “firm belief,” “creed,” “conviction,” or simply as “religious,” depending on context.

Some will also use this to mean “trust in God” in Japanese (though the term for God is not actually in this title).

It should be noted that this word is a little strange alone on a wall scroll.

While this can be pronounced in Japanese, it’s not a great selection for a wall scroll if your audience is Japanese.

Depending on the context, 教友 can mean Christian or “friend of the same religion.”

While technically, it could be any religion, this is used mainly within the Christian faith. You can also translate this as “Christian friend” and, in some cases, “Church member.”

信仰と希望と愛 is a Japanese list of words (not really a phrase) meaning faith, hope, and love.

Some have associated this word list with Corinthians 13:13, though there are no specific religious connotations in this word list, and it's not directly from that Japanese Bible verse.

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

神の信仰 is the simplest way to express “Trust in God” in Japanese.

The first character means God, deity, divinity, or spirit (in this case, it will be read as God).

The second character is a particle that links the ideas.

The last two characters mean faith, belief, or creed in a religious context.

信心 is a Chinese, Japanese, and Korean word that means confidence, faith, or belief in somebody or something.

The first character means faith, and the second can mean heart or soul. Therefore, you could say this means “faithful heart” or “faithful soul.”

In Korean especially, this word has a religious connotation.

In the old Japanese Buddhist context, this was a word for citta-prasāda (clear or pure heart-mind).
In modern Japan (when read by non-Buddhists), this word is usually understood as “faith,” “belief,” or “devotion.”

These Japanese Kanji, 安心立命, can be translated as “religious enlightenment” or “spiritual peace gained through faith.”

Other dictionaries define as “spiritual peace and enlightenment” or “keeping an unperturbed mind through faith.”

My Buddhist dictionary defines it as “spiritual peace and realization of enlightenment.”

In the Zen school, this is about settling one's body and life; attaining complete peace, and establishing one's course of life in accord with the ultimate reality.
