you probably will not find the cahracteristics of the True Church in the cathecism Friend, by True Church of course, by Biblical deifinition, is the Body Of Christ, the Followers, people

but the Bible does tell us the characteristics of the True Body of Christ, I will provide for you and you can check it out for yourself for your own conclusions

(Hebrews 11:37, 38). And hide they did--the Waldenses, Albigenses, Huguenots, and many others. God's people (His church) would have been obliterated if they had not fled and hid in the wilderness during this devastating persecution by the papacy. (In one 40-year period, "from the beginning of the order of the Jesuits, in the year 1540, to 1580, nine hundred thousand were destroyed. One hundred fifty thousand perished in the Inquisition in 30 years." 1) At least 50 million people died for their faith during this 1,260-year time period. God's church did not exist as an official organization during this 1,260-year time period. From A.D. 538 to 1798 it was alive but not identifiable as an organization. When it came out of hiding after the 1,260 years, it still had the same doctrine and characteristics as the apostolic church, which entered the "wilderness" in A.D. 538.
Many fled to America to escape the terrible persecutions of God's people.
There are many loving, genuine Christians in churches that were officially in existence before 1798. But none of these churches can be God's end-time church into which Jesus is calling all His people, because Jesus' end-time church had to arise after 1798. This means that most of the popular Protestant churches cannot be God's end-time church because they existed officially before 1798.
It would keep all the Ten Commandments, including the seventh-day Sabbath of the fourth commandment (John 14:15; Revelation 22:14). It also would have the "testimony of Jesus", which the Bible tells us is the spirit of prophecy (Revelation 19:10). Remember that while hosts of sincere Christian people are found in churches that do not keep the Sabbath or have the gift of prophecy, none of these churches can be God's remnant end-time church into which Jesus is calling all last-day Christians, because God's end-time church will both keep God's commandments and have the gift of prophecy.
God's judgment is in session. Worship Him! God's end-time church must be preaching that the judgment began in 1844 It also calls upon people to "worship him that made heaven, and earth, and the sea, and the fountains of waters." Revelation 14:7. How do we worship God as Creator? God wrote the answer in the fourth commandment. "Remember the sabbath day, to keep it holy." "For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it." Exodus 20:8, 11. So the first angel's message commands all to worship God as Creator by keeping holy His seventh-day Sabbath, which He gave to us as a memorial of Creation.
the six points that Jesus gives us for identifying His end-time remnant church:
Unless a church is preaching the three angels' messages worldwide, it cannot be God's remnant church for the end time.
1. It would not exist as an official organization between A.D. 538 and 1798.
2. It would arise and do its work after 1798.
3. It would keep the Ten Commandments, including the seventh-day Sabbath of the fourth commandment.
4. It would have the gift of prophecy.
5. It would be a worldwide missionary church.
6. It would be teaching and preaching Jesus' three-point message of Revelation 14:6-14.
The Bible says there is only one true body, or church (Ephesians 4:4; Colossians 1:18).
The Bible says our day is like Noah's day (Luke 17:26, 27). How many ways of escape were there in Noah's day? Only one--the ark. Once again, today, God has provided only one boat, or church, that will take His people safely through to His heavenly kingdom. Be sure to get on the right boat! The Bible says, "The Lord added to the church daily such as should be saved." Acts 2:47. It was true in apostolic times; it is still true today.
