Yes. But I do not take the paragraph in isolation. I think the brothers were wise to include for clarity and balance this additional statement.
In order to be saved, one must have a living contact with Jesus Christ. Therefore, in bringing unbelievers to salvation, we emphasize prayer and calling on the name of the Lord. According to Romans 10:9 and 10, if a man is to be saved, he must believe in his heart and confess with his mouth.
Furthermore in receiving one another it says we should receive those who are weak in faith.
"Now him who is weak in faith receive, but not for the purpose of passing judgment on his considerations."
For example - the reigning of Christ on the earth indicated by these words in the pamphlet -
that He has been exalted to the right hand of God and made the Lord of all; and that He is coming again for His own and to set up His kingdom on earth.
It some earlier stage of a Christians' maturity he may not be clear about the reigning of Christ on the earth. Perhaps he thinks he only "goes to Heaven" forever.
I would consider this immature in understanding or weaker in faith.
Of course eventually, imo, he will include this aspect of salvation.
