Casa de Cristo Evangelical Church was originally founded in the fall of 1970 as The Phoenix MCC (Metropolitan Community Church). It was the first MCC to be established outside the state of California.

That church was fire bombed in 1977 and all the early records of the church were lost. It should be noted that the church was not always evangelical in nature and even the original purpose for forming the church is somewhat unclear. In the early days it appeared to be very political and more or less a social club.

The church has had many pastors in the past with varying backgrounds. Consequently, the church went through a series of transformations. At first, the services were of the high church tradition, so much so that the church resembled a Catholic Church.

Fred L. Pattison (pastor 1977-1996) was the first pastor to come from an evangelical background and he introduced the "Baptist" style of service into the church. He was the first to preach the plain and simple gospel of Jesus Christ and the necessity for each person to be born again. Under his direction Casa de Cristo became known throughout the nation and beyond as a strong biblical church and a strong defender of the historic biblical faith. He was a strong believer in the necessity of biblical morality.

The land upon which the church sits was acquired in 1977 after the destruction of the old building and in January of 1978, construction of the new sanctuary was begun. Joseph Sombrio, the pastor's spouse, headed up the building team and the church dedicated the completed facility the first Sunday of the following October. One hundred seventy-eight people jammed into the sanctuary attending the 3-hour dedication service. The sanctuary has been remodeled twice since then. It was first remodeled in 1992 and again in 1997 to accommodate growth.

Just to the left of the platform in the sanctuary is the Prayer Chapel which is used for quiet prayer when the building is open. It was used as the church office when there was only one building.

Ashby Hall (formerly known as Cristo Hall) was added to the sanctuary in 1984 with the help of Mr. Sombrio and a few other volunteers. This portion of the main building is a two-story structure with a kitchen, pantry, and restrooms on the first floor, and meeting rooms plus a small office on the second floor. Judy Tall Wing McCarthy, a Navajo Native American artist who was a member of Casa at the time, painted the two large original murals on the walls in Ashby Hall.

The property to the east of the parking lot was purchased in 1988. There are two buildings on that lot. The first building contains the church offices, the Senior Pastor's study and the Genesis Counseling Center. The second building houses the children's Sunday school room and the library. Located between the two buildings is a Memorial Garden dedicated to the memory of those who have died of AIDS.
